Oddly enough, this mapping also takes over plain old control-g, which is fine for me.

There's nothing odd to that: in "cooked" input mode (as used by Vim), Ctrl-G and Ctrl-g both (by design) map to the BEL character, 0x07. This applies to any Ctrl+letter combination: in ASCII (not EBCDIC), Ctrl+letter = (letter AND 0x17) where "letter" is in the range [a-zA-Z].
