You’re still missing what’s been stated elsewhere in the thread: that OpenBSD’s review process is VCS‐agnostic, that the project officially mirrors to GitHub, and that many developers and external contributors use the Git mirror for their work (just look on the tech@ list for how many mails have “diff --git” in the patch).

Myself, I’m crazy about local branches and rebase -i. But it’s no skin off my back if the final command I run winds up being “cvs ci”.
