The correctly packed repo is closer to 500MB last time I checked.

That’s an optimization problem IMO, and optimizing should be done for the main use-case.

Moving to GitHub does not automatically mean we will accept pull request. This will be another discussion after the move, so don’t hold your breath on it for now.

But seriously, we have multiple options to contribute available right now:

-  `arc diff` will upload directly to phabricator
- `git format-patch` (or `git diff`) and upload manually to phabricator
- `git format-patch` (or `git diff`) and email to llvm-commit

That shouldn’t prevent anyone from submitting a contribution.
