Ah, right, at Sun we used MQ. But anyways, just glancing at the hg evolve docs I'm unconvinced. And anyways, it's an "extension". Mercurial fought rebase for a long time, and they did dumb things like "rebase is non-interactive, and histedit is for when you want to edit the history".

And that is partly why Mercurial lost. They insisted on being opinionated about workflows being merge-based. Git is not opinionated. Git lets you use merge workflows if you like that, and rebase workflows if you like that, and none of this judgment about devs editing local history -- how dare the VCS tell me what to do with my local history?!
