Because I cannot stand it --
Let's just suppose, for the sake of argument, that this will involve a grand slam decision, as this appears to be the end question anyway.
Assume my start of:
1♥-P-2♣-P-
2♦-P-2♥-P-
?
If using my type of cuebidding, Opener will on many gran-slam oriented hands now bypass 2NT (as 2NT would have denied two top hearts, bypassing 2NT promises two top hearts) to cuebid 3♣ (one of the top three honors, obviously the King). Thus:
1♥-P-2♣-P-
2♦-P-2♥-P-
3♣-P-?
Responder knows that Opener has AQxxx at a minimum in hearts, solidified by the King to yield an expected five tricks. Opener's club King yields four more club tricks, for nine tricks so far. The spade Ace is the 10th. If Opener has Axx+ in diamonds, an easy thing to ask, then it seems that an 11th from the diamond Ace is easy, as is a 12th from just one diamond ruff.
Responder cannot now show a diamond card (A/K/Q), so he bypasses 3♦ to show the third top heart (3♥), erasing the need for anyone to bid 4NT as simple keycard.
This start is already powerful.
Where problems might occur includes a scenario where Opener has, for instance, the KQ in spades and we can establish spades. That problem might be mitigated by a 4♠ call from Responder, after all three top hearts are shown to be held, as "RKCB" but focusing on the diamond K-Q rather than the known heart K-Q.
Another plausible situation would be where Opener's diamonds are solid, allowing a ditch of all clubs (but the Ace) from dummy, but, although that might also be handled, this does not seem to be a plausible problem.
Of course, these tools might not be available, which might reduce the effectiveness of a proposed 2♣ start.
