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.
