I don't think that is necessary. We already have *two* options to
force-push a ref: the + in front of refspec, and --force.

IMO, the meaning of + should be changed to "force-push with safety", and
--force can then be used to override if the safety triggers (i.e., --force
is your extra-super-force option).
