Even more so, yes, because the choice between completion and cycling
is not just a preference for this one.

I'm not sure.  We could try and provide key bindings for all those
commands, but that would seem close to impossible: we're talking about
keybindings that would mostly need to be very short (single-key) to be
worthwhile, and we really don't have that many single-key available.

So, I see it as an implementation problem where we want to make
in-buffer completion modal to some extent: when in-buffer completion is
started you'd be put into a new "mode" (kind of like isearch, I guess),
where new completion commands become available.  The main problem is
how/when to leave this mode (it should be as seamless as possible).
Some other reason for such a change: we want to be able to run code when
completion is finished, e.g. to hide the *Completion* buffer.
