While I think encouragement and enforcement are different things, the point about C-g is more what if the user *also* binds keyboard-quit to "7". In this case the user expects 7 to call keyboard-quit, not just C-g.
Also as Eli said ESC ESC is supposed to keyboard quit I think.
But main thing, as in life, better to look for what what you want than control for what you don't want.
