Well, I think the definitive answer is probably the usual "who knows
what anyone's doing with zsh features?"

But my gut feel is compctl only ever got to the point that it was doing
simple local stuff that finished quickly, and we're morally entitled to
assume that anything that isn't like that is using compsys.  So I'd be
inclined to try what you suggest and just make sure a few simple builtin
completions with compctl work.
