Just opening up a conversation about how to do this. This would be a really nice feature for deffirential.
From Facebook Tasks:
D255317 fixes (or at least should fix) the latest branch, which means we can get a working build out for testing.
Right now though, we need to get it reviewed, committed, and requested for merging in to latest.
I'd like to be able to request a diff to be merged, prior to it actually being committed. This is a valid thing to do as long as we're not using shadow branches in production (and only for testing), though I guess that might be debatable.
