IIRC VC was given some significant surgery around the time where Emacs
was migrated to a Git repository in order to better support file-set
check-ins and various workflows for distributed version control systems.

I seem to remember that some RCS-only features were debated and possibly
dropped at that time because ESR (along with a lot of others) were not
terribly sympathetic towards complicating the generic framework because
of the possibility of its continued use (mostly expected to be due to
nostalgia).  Indeed, I switched to using Git even for private one-person
projects a long time ago myself.

So I would not be terribly surprised if Eric happened not to be overly
enthusiastic about reintroducing RCS-only functionality that was weeded
out for reasons of practicality.
