It's better than keeping the functions separate because the separation contributes in a significant way to making the interface a hairball that is difficult to understand and maintain.
Would that make the combined function's description shorter than the current `dir-status' one, in vc.el header? If yes, how?
I suspect that would make the details from `dir-status-files' get lost in the noise, whereas I like its "report on all requested files" semantics (here's why: https://github.com/dgutov/diff-hl/issues/25#issuecomment-57107335).
Even now, when the description is separate, almost every backend I tried currently fails to adhere to it in some respect, see http://debbugs.gnu.org/cgi/bugreport.cgi?bug=18579#5 and http://debbugs.gnu.org/cgi/bugreport.cgi?bug=18579#59.
I should have been able to write SRC support in 90 minutes. The fact that it took the inventor of both SRC and VC mode *two days* told me the API has gone very badly wrong.
Some things are just hard. And, backwards compatibility aside, usually we don't want to discard existing features.
