Package renaming?

The topic was touched by @Azzaare in https://www.youtube.com/watch?v=G4siuvNMj0c (nice talk, by the way!).

I'm not sure that the contents of this package will be merged soon into MOI, a better name (to indicate closeness to MOI, at least) would make finding this package easier for users. For now, it looks a lot like a name for an experiment (which it was in the beginning). Also, it would be good to have a shortcut for the package (Jean-François proposed CPE). Currently, I'm using a lot either CP or COIx for subpackages (to mimick what MOI does).

Maybe something like ConstrOptInterface? It looks a lot like MOI (which is intended) and is roughly pronunciable. It could be shortened to COI (in French, though, this is "quiet; speechless"; I just hope it's not too vulgar in another language).

Or is the current name completely acceptable for the foreseeable future?

Review the proposed package names, the linked talk, and the relationship to MathOptInterface described in the issue. Done means the maintainers reach a decision on whether to rename the package and, if so, agree on its name and shortcut.
