I'd like to propose that r.cost be changed to eliminate the "dual use"
of the "output=" option, by adding a separate "start_rast=" option. If
none of the "start_sites=", "coordinate=" or "start_rast=" options are
given, an error would be generated.
Any objections?

None here. That behaviour is atypical of most modules, and could be a
nasty surprise for the unwary. Generally, I think, modules
should not overwrite existing data. There are a few exceptions,
but better to force the user to make a conscious decision to
run g.remove rather than let an accident ruin someone's day.
