Right, so the question is: how should the generic code make such
flexibility available (and conversely) how shojuld the client of the
completion code be able to exploit/provide such flexibility.
I'm very interested in adding such hooks into the completion code, but
I haven't come up with any convincing idea of what they should look like
(the closest I got is completion-annotate-function which is very
limited). So suggestions are welcome (patches as well, of course, tho
it's not crucial).

Of course. company-mode is an obvious example.

Would that be like IDO's C-SPC (aka ido-restrict-to-matches)?
It shouldn't be too hard to add that to the default completion.
Maybe even without having to change minibuffer.el (i.e. there should
already be enough hooks for that).

That would be like the minibuffer-exit-hook, but for completion inside
a normal buffer, right? That sounds like a good idea. Currently,
figuring out when such "inline completion" ends is actually pretty
difficult, but it's something very much needed.
