I mean '21st century'.

There is difference between turning the buffer into read-only and the
file on disk being read-only. VC backends depend on the latter for their
status based on my experience with RCS. So showing such a message does
not make sense when pressing C-x C-q. It might make sense when opening a
read-only file that is also under version control. But even this point
is mostly irrelevant since 75% of the vc-handled-backends, which
hopefully represent 99.9% users, need not such message.

I just recalled when I was beginning with vc. I did once foolishly
follow that message and wasted myself a few unhappy hours fixing the
consequences.

Just some thoughts.
