You're the first person, that I'm aware of, to suggest that we should restrict commits to master and require all contributors, including those who have already been vetted and given commit access, to make their contributions through pull requests. I'm sure there are other projects that have made such policies, but we haven't so far. Instead, we allow direct commits to master, and we encourage others to review those commits on the macports-dev mailing list or on GitHub.

We've only been on GitHub since late 2016. For the 10 years prior to that, we used a Subversion repository, and prior to that it was CVS. The only way to update those repositories was for a someone with commit access to commit to them. Many of us who were MacPorts committers during that time are used to this way of working and might find the additional roadblocks to our contributions that pull requests represent to be intrusive. In my case, I feel like I might finally be becoming proficient at submitting pull requests at least, but it has been a long and frustrating learning process for me, and one which is far from over; I'm still making git mistakes daily.

We've only had our Travis CI integration set up since mid-2017. I am not certain what its reliability is now. Often, when I've looked at a Travis failure log, it has turned out to be a problem specific to Travis, and not a reason to reject a PR. So I am not paying a great amount of attention to what Travis is doing at this time. It's nice that we have it, it's nice that our other developers like to use it to check their work before publishing it. But developers are already expected to check their work and verify the port installs on their own machines before committing or submitting a PR or patch; if they do that, they shouldn't see much on Travis that they didn't already know about.
