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. --=20 David Kastrup
