Indeed, you could be right that always one-for-all completion function
might be made enough for the prefix completion. But I don't see how popup
menu can properly deal with partial completions for example, or
expansions a la yas. So you would still need a separate list for those.
And the old argument still stands - would the user like to have the same
redundant list of completion functions for C-M-i and popup menu?

Maybe -c-a-p, or -c-a-p-data?
