You've been misreading my comments apparently. Full disclosure applies to your opponents at the table and I've clearly stated that I would give a complete description for the alert, etc. It doesn't require you to ask the regulators about your conventions in any particular language. If I know they'll auto-deny anything with the word "MOSCITO" in the title (which is pretty close to accurate), I can just ask about your system calling it "New and Improved MOSCITO" and get them to reply that this is not allowed. Now I'll do this for every system I don't like and try to get each team sanctioned for playing those methods, despite the fact that if they may have also asked about their system in a different way and gotten it approved.

"Catchall" is defined in the context of a system, referring to everything else you don't open something else. In my more-like-MOSCITO-than-Owen's GCC system proposal these are equivalent. What exactly do you mean I "don't open any hand with 1♦ anymore"? Do you think that there's some particular hands you must open 1♦ with under the all-purpose GCC provision, because it sure doesn't give any indication of such in the rule text. Every single system opens 1♦ with some hands and not with others, and catchall is just a convenient name for a wide range of hands that don't fit elsewhere.

It's as completely different as a 0+ precision opener is from a 2+ precision opener is from "unbal, promises a 4cM", all of which people play under that rule now in strong club systems. Each of contains a bunch of hand types and at least 10 points. And remember here in the US defense is your opponents' problem, not yours, since a legal GCC opening requires providing no defense or anything similar. Just alert and explain, and if the opps aren't prepared for that particular conventional opening, well, that's their oversight.
As an aside along the lines already mentioned, 1♦ showing 4♠ unbal or a "Gambling 3NT" opener (solid 7+ minor) should fit the 0+ definition just fine under even the most picky reading of GCC. It promises 0 cards in any suit - just a bunch of misc hands with 10-14 points not opened anything else.
