I'll further the debate. Fred, you can sneak a peek but refrain, if you want.
Here's the "other problem" I see to this hand.
Suppose you do start 1
♠. If partner raises you, you end up in the strange nether-world of invitational/slammish next calls and other auctions that few find easy. This should be better than the alternative, admittedly.
However, if partner does not raise, you end up with several problems.
First, partner will undoubtedly bid 1NT quite often. Quite often, then, my cards will be on dummy. I'm not sure that this is good.
Second, after 1NT, I have a tough rebid. If I do bid 3
♦, this seems worse than the "pattern out" problem with a 2
♣ opening, because my diamond length is wildly unknown. I might have a fragment, or I might be 6-4, or I might have 5-5, or I might have this hand.
Once I do bid 3
♦, I'm not sure that I do much to get us safely to 3NT. If partner is concerned about 3NT after I show a 21-count, how sure will he be about side stops when my hand is all the more likely to have COV problems?
I mean, every single point of problem that I see with 2
♣...2
♠...3
♦ seems tame in comparison to the problems after 1
♠...3
♦, and we end up at the same level with less assurance of diamonds as real and more concern over whether Opener has a problem hand.
Contrasting this is the idea of 2
♣...2
♠...3
♦ as a more powerhouse, heavy COV hand, but that holding seems RARE as heck, and one where I can stand the occasional 4
♦ rebid.
Add in the 1
♠-P-P-P making four problem.
But, maybe this is a matter of style.

And we ask police officers, prosecutors, defense lawyers, and citizens to enforce or abide by it? The legislature continues to write unreadable statutes. Gibberish should not be enforced as law."
