I think at one point in this thread someone suggested that "at most 2 doubletons, and generally no singletons" allows for the possibility of opening an 8-2-2-1 hand with 1NT. It has 2 doubletons and 1 singleton, and could be among the occasional exceptions to the "generally no singleton" criterion. But anyone with an ounce of sense understands that when they said "at most 2 doubletons" they actually meant "at most 2 suits of 2 cards or less". It also doesn't say anything about voids at all, but it doesn't need to -- everyone knows that a hand with a void is unbalanced.
I believe that the purpose of that bit of the GCC is not to be the precise, legal definition of what is "balanced". Bridge players already have a general notion of this, but it's kind of fuzzy, and different players may use it somewhat differently: we have square hands, semi-balanced hands, etc. So the point of that clause is simply to say that the GCC uses a relatively broad definition of balanced for allowing NT openings. But no one with any bridge experience needs the GCC to tell them whether 8221 is balanced or not -- it's clearly not. Interpreting that description in a way that makes it balanced is just ludicrous.
This question is easily resolved by changing the definition of "balanced" in the GCC, and also changing the requirements for the 1NT opening "generally". Like this: "A balanced hand has 4-4-3-2, 4-3-3-3, or 5-3-3-2 distribution. A semi-balanced hand has 5-4-2-2 or 6-3-2-2 distribution. All other hands are unbalanced. A natural 1NT opening is generally balanced or semi-balanced, but may occasionally contain one singleton (which implies 4-4-4-1, 5-4-3-1 or 6-3-3-1 distribution). A natural 1NT opening may not contain a void." You could change "one singleton" in that last sentence to "a singleton A or K" if you want to make it more restrictive.
Before somebody points it out, I'm aware that this is not precisely what the GCC currently says, nor is it how some interpret it.
