In some cases full disclosure has to be advance disclosure. If we have 15 minutes to play two boards, handing us a sheet containing a dozen highly unusual conventions doesn't help much -- we won't be able to discuss and work out good defenses in the time allotted, and the particular pair playing the unusual methods will never finish their rounds on time. For long team matches where pairings are known days in advance, it's reasonable to play "anything goes" but this applies to very little except perhaps the Bermuda Bowl.
As far as the ACBL Convention Charts go, re-working the charts from the ground up isn't really feasible at this point. I'd suggest making the following changes:
General Chart:
(1) Clarify the status of natural openings. I suggest adding "Natural openings which promise ten or more high card points" under allowed openings, as well as "Openings at the two-level or above which promise five or more cards in the suit named and have a range of at most seven high card points." This will explicitly legalize natural openings that most of us use anyway.
(2) Clarify the status of natural responses. In particular, I'd like to see "Responses which show three or more cards in the suit named" under allowed, which covers for single raises and for folks who have the de facto agreement to respond 1M on three-card suits with some patterns to their minor suit openings.
(3) Remove the prohibition against playing "methods" when opening 1NT which could be less than ten points or too wide a range, or opening at the two-level with too wide a range. These were clunky and poorly-defined. The new laws allow regulation of natural calls, so instead simply ban the undesirable openings. In other words, 1NT openings must promise 10+ points and at most a five point range and two-level openings which could be weak must have at most a seven point range.
(4) Remove the prohibition against "relay systems" and against "1NT response showing invitational or better values." Both of these are poorly defined and rarely (and unevenly) enforced. They both have ridiculous "get arounds" (such as including some very unlikely weak hand type in the 1NT response, or arguing that the "relay" bid actually shows something due to highly unlikely relay breaks). Note that most "relay systems" that are non-game-forcing are banned by the illegality of artificial non-game-forcing responses on the general chart, and that most game forcing relay systems are allowed in practice (at least in my experience of the rules on the ground).
(5) Clarify the meaning of "all-purpose" minor suit openings. Personally I believe this to mean "any meaning, as long as 10+ hcp" but some people apparently differ. It may even be reasonable to restrict it to "any combination consisting only of natural hands, balanced hands, and hands with 15+ hcp" if we want a more restrictive chart that still allows simple precision and polish club type methods.
(6) Legalize 3NT opening showing a sound preempt in a major. This is easier to defend than namyats and has been around for ages (I think Danny Kleinman wrote about it years ago).
Mid-Chart:
(1) Allow calls which show five or more cards in a known suit. These are not that hard to defend; an easy defense is for double to be takeout of the suit shown, the cuebid of their suit to show the canape hand type with 4M-longer minor (one suit will be known as it's not to include the five card suit showed by opponents) and otherwise treat as natural. This legalizes a wide range of easy to defend methods.
(2) Allow calls which show either five or more cards in a known suit, or some type or types of strong hand (15+ hcp, but which may not include the known suit). The same defense above is reasonable, and again this legalizes a wide range of easy to defend methods.
(3) Amend the list of "allowed" conventions by removing from the list the specific methods legalized by the two statements above, and by the legalization of natural calls on the general chart. This actually covers almost all the specifically-listed things except for multi type openings.
(4) Remove all mention of "relay systems" from the chart -- again, these are poorly defined, rarely (and unevenly enforced), and have ridiculous loopholes.
(5) Allow any defense to 1NT openings, and do not require a pre-alert for those defenses which are not permitted on the general chart. Methods like Woolsey and Multi-Landy are very popular at the mid-chart level (and most people don't pre-alert them anyway).
(6) Allow multi, even in two-board rounds. The fact that multi is banned in the Reisinger is simply embarrassing to ACBL, as this is a convention which is popular world-wide. To simplify matters, I suggest having only one defense to multi in the defense database. Obviously players can bring their own defense and refer to it during play, but the existence of two official defenses creates unnecessary confusion (i.e. pairs who don't agree which defense to play before the auction starts, pairs who take a long time deciding which defense to play, not to mention that defense two is very complicated and has some "holes" in it).
