We've uncovered an interesting scenario with PRs. We have two conflicting solutions for one problem, both in a PR:
Things that might help:
- being able to link the two PRs in some way, similar to issue links so there's something prominent calling out the relationship
- being able to treat the reviewers on both PRs as one group
- people have done things like email me directly, because there's no way to reject or downvote a PR
Both of these can be done with comments, but I'm finding this just isn't working on the social side. I've asked people to comment, I've emailed, pinged on IM, etc.
Although I've suggested some specifics; really this feedback is "it would be nice if BB had a good way to resolve competing PRs" with a side order of "people seem to want a Reject button as well as an Approve button".
