Stacked commits is awesome, but it sucks that with git you need all these workarounds, and that the servers (GitHub etc) are not designed with that workflow in mind.

I left Google a few months back to work on another project. I missed the internal version control so much that I dropped that other project and am now focused http://twigg.vc It's very similar to what's used at Meta and Google. Atomic commits, linear history, auto rebase, code review compatible with stacked commits.
