"just" - I bounced off Phabricator because I couldn't use native git tooling, and what mapped to where wasn't clear to me. The pure git approach of git-pr is the exact opposite of that. Sure, someone is going to write just-too-useful-to-skip-wrappers around that later, but you always know what's going on under the hood.
