I don't think the case of "force push" is very different from the
"non-force push". If you're surprised that "git push -f" pushes
everything, most likely you didn't want a plain "git push" to push
There are already several measures against this. The first is mentionned
in Jonathan's message: Git 2.0 will only push one branch by default (-f
or not). You can already get this behavior by setting push.default (if
your Git version is too old, set it to "current" for example, read "git
Another measure is a better documentation. We've just merged the change
below. In short: don't run "git push -f", but run e.g. "git push origin

Documentation/git-push.txt: explain better cases where --force is dangerous

one remote ref, but running it when pushing several branches can really
be dangerous. Warn the users a bit more and give them the alternative to
push only one branch.
