   I also, by the way, removed the "editable" flag on the checkout
   capability; where it matters (SCCS and RCS) files are now always
   checked out editable.

Maybe you can move that functionality into those backends.  I use a
RCS- (and CVS-, for that matter) controlled file's read-only status
in my workflow.  FWIW, locally, i've kludged Git to work similarly.
