Grafts allow you to do a bunch of other neat stuff. I use Git as a backup system for SQL dumps, but since the repository will grow a lot I want to throw old dumps away. So I just create a graft and rewrite my history so that it only contains 7 commits (7 days): git rev-list HEAD | sed '7q;d' > .git/info/grafts && git filter-branch -f HEAD
