I would suggest that singletons and doubletons are excluded from consideration. because they don't have about the expected length and strength ( everyone expects 4+.).
There are 2 cases,
1) major suit >= 4 cards
2) major suit < 4 cards
If you have less than 4 cards, you don't have the expected length. I don't see why you want to discriminate against doubletons, singletons and voids. They should have respect.

The ACBL allow3s for canapé systems to be played. Surely they don't intend that canapé players have to search for 9 card Major fits...or if that is their intention, then they may as well ban canapé systems from tournament play vs. hobbling it
I play Blue Team Club which uses canape and I have no problems playing in tournaments. I don't open 3 card majors and in fact, 3 card majors was never a part of BTC, although it was a feature of Roman Club. I'm pretty sure I read about Roman club being legislated out of existence (in its original form) by the prohibition against opening 3 card majors. You don't need to open 3 card majors to play BTC, and you sure don't need responder to bid 1
♥ on a 3 card suit to find a 5-3 major suit fit. If opener bid 1

(Not to get distracted, but playing 5 card Majors, if one opens 1M and is raised to 2M by partner, why is responder not required ro have 4 cards by the GCC definition ?)
As you have noticed, the GCC is very poorly written. My guess is that nobody considered that a raise was also a response (which requires 4 cards in a major) and then forgot to specifically mention raises. Suppose opener opens with 3
♠. Certainly you would have no problem raising to 4
♠ with a singleton or even a void with
Also, what about raising a NT opener, e.g. 1NT - 3NT Notrump raises are undefined.
