I just read the docs, which claim there is a good reason for file-
oriented VCSes to come first.  If the docs are wrong, they should be
fixed.

As far as I know this has always been rare.  The whole idea is quite
possibly obsolete according to what you say about the actual behavior
of vc, but if anybody still cares the change you're suggesting will be
a subtle change in behavior that will be intermittent and possibly
hard to diagnose.  I've found that it's almost always better to change
DWIM to "do nothing" as opposed to "do what somebody else means".

AFAIK it will also do this if it's controlled by no backend, too.
