No, actually VC did make buffers read-only based on the backend's status
rather than just based on the file's own read-onlyness.  And C-x C-q was
used by many people as the main way to interact with VC (both to check
out and to check back in).  I know it all sounds really odd seen from
today's point of view, but it still made sense in Emacs-21, which isn't
that old.
