So-called Marmic-hands with a 4-4-4-1 distrubution can be a pain to bid.
With my regular partner I have agreed to open all 11-19 point Marmic hands with 1♦ - even if the singleton is ♦.
Depending on the answering bid from my partner, I am mostly able to show the hand in the next bidding round, either by supporting my partners suit, bidding a new suit or by bidding NT.
I am sure there are many similar agreements in other systems.
Naturally you have to alert the 1♦ bid, but my question is: is this kind of opening bid illegal (or what I think is called "highly artificial"), since the hand might hold a singleton ♦?

I doubt it's illegal. You see strong club systems with short diamonds all the time (some even 0+ diamonds). There shouldn't be any problems provided you disclose it properly (is 4414 the only shape where diamonds can be short?)

Again, what jurisdiction are you asking about? In the BBO Main Bridge Club, everything is allowed.

It would be alertable in the ACBL (and most other places, I imagine) but legal. Artificial, yes. But not a Highly Unusual Method, as the WBF terms it.
The banned bids are generally ones that show extremely weak hands at the 1-level, or show weak hands but don't specify a suit at the 2-level. Bids to show full openings are legal most places, though artificial use of 1 of a major is sometimes allowed only in certain events. Almost any meaning of 1C or 1D is allowed.
