PS: about the role in git: I don't feel that strongly about it, but I think master is somewhat more descriptive. The master branch contains the most up-to-date version of the source code, so e.g. if I'm working on a feature branch and a colleague pushes a bug fix that affects me into master, I need to merge/rebase to get the latest changes into my feature branch. So, while the master branch doesn't "rule" the feature branches, there is still the implication that changes to master should find there way into the feature branches at some point, which I think main doesn't convey that clearly.
