It's good to have this feature, but it is still up to the individual developers to separate the PR work in a way that can be merged "all or some and in which order". It can make organizing, reviewing and rebasing easier but a PR with repeat, broken or overriding code can screw up just the same. I guess what I mean is, don't expect it to just sort out multiple PRs that wouldn't have worked together without it.
