John, We understand the bylaws. But, practically we saw master in an unusable state for many months. This is not just about trust. CloudStack is so vast that its difficult for a single person to test all the affected areas. Many a times, people does not even have enough hardware/knowledge to run integration tests. Bugs which are found at a later point of time have very high cost. Finding that commit which broke something is very hard task. Rolling back is the easiest part of it.
In an ideal world, we could just allow everyone to commit (maybe we could even allow non committers to commit and increase the velocity). But, it did not workout. which is why we have all these rules based on previous learning. For 4.6, we did not start with RM only merges. But, after many failed attempts we came to that conclusion. Watching the branches and policing is more difficult than allowing only a few people to commit. I do understand Rohit's concern about RM being bottleneck. The initial idea was we will have more than one RM(may be around 5) so that one of them would be available always. But, given the amount of time it takes to do the RM job, we did not get enough volunteers. Even now, I dont think its the RM that is the bottleneck. But, its the number of people with real hardware who are willing to run integration tests for the PRs. Most of the efforts of RM goes in setting up test environments, running tests, bringing the results back to PR. Maybe, we could follow a middle ground like this. We as a community can authorize few more people to merge PRs in addition to RMs. How do we select these additional volunteers? Any committer can just come forward and declare(in a mail to dev@) that he read the release principles[1] and would like to volunteer to commit.
