Besides a wrong push, the reflog gives you all that albeit not very intuitive. I admit that I often put tags at the current stage before trying anything advanced in order to find the last known good state easier. Undoing a wrong push involves so many corner cases that it would be hard to implement. Where I work we are using gerrit and the default project setup doesn't allow direct pushes. Than it's only abandoning a change. When I started working with git I came from Perforce and CVS. I had the complete wrong mental model in my head because of this which got me trouble understanding why things where not working as expected especially when pushing to remote.
