The particular kind of dynamic completion it provides is not provided by
anything else, AFAIK, and that feature is useful.

I don't use it anymore, personally, but I used to use it a lot.  (There are
several useful Emacs features - calendar... - that I used to use a lot but no
longer use, for whatever reason.)

Wanting to reuse the `completion-' prefix for something else is not a very good
reason to deprecate.  And any "namespace" cleanup such as you describe is pretty
much a nice-to-have for a library that presumably is not used much.

So my vote would be to (a) to keep completion.el, (b) add a FIXME note, if you
like, with suggested namespace-related changes, and (c) use some other prefix
for the other, unrelated code.  Unless, that is, there is a replacement for
completion.el that does the same thing or more.

Just one opinion.
