At Apache OpenNLP we just established among committers that you check that the status indicator is green before you merge, and if it wasn't the case then we would ask the committer to take responsibility and repair things. Works very well our build is never broken.
We also strongly prefer if each PR gets reviewed by another committer. Overall this works quite well. We don't use any of the protections against merging, it is important that you can trust each of the committers not to break things, if there are problems it is better to resolve them with talking to each other, rather than enforcing green status checks.
