Another use is as an alternative to a force-push that doesn't cause non-fast-forward changes for others.

E.g. you want to revert an incoming (stupid) commit, but you don't want to do git push -f because then you'll spend the next half-hour guiding your client through recovering from that, and you want a shorter alternative to

git checkout -b temp remote/origin
git revert HEAD
git push temp:origin
git checkout master
git merge origin/master

so you simply do

git merge -s ours origin/master
