I can’t speak for the developers, but I guess that Python has just taken over and is undoubtedly a “language” that unifies most VFX pipelines these days.
To keep C.O.F.F.E.E. alive would mean, to write for anything new inside the application, even changes, the part for C.O.F.F.E.E. as well. Otherwise, it wouldn’t work at all anymore. Since this is practically to mirror the whole application, it is not just to leave this old code inside, it is a lot of work, viewed from my personal point of view.
