Good.

A sorted array of pairs of symbols, perhaps? (<fn, mode>, or the
reverse, <mode, fn>, with `mode' being `nil' when the function is not
restricted.)

Annotating the functions is no small task, indeed. There are quite a few
traps. However, my experience with ido+flx convinced me about the
potential value of an effective M-x which, for commands that you use a
few times a day at most, requires far less cognitive load than using its
keybindings (when they have one) or M-x with the default completion
system.
