I think the issue here is that the change occurred very quickly after the
branch, and when users wanted to 'change gears' back to RELENG_7 from HEAD
once it was created immediately ran into the problem. It seems like a useful
piece of post-branch advice to developers in the future will be, "Please don't
do things that make switching branches -- back or forward -- for the first few
weeks after the branch is created". In general, I don't think we care about
forward compatibility, but we are currently getting lots of reports because
this is one of those few times where a lot of moving backward happens.
