primary/secondary and leader/follower make just as much sense, and avoid any discomfort. For IDE, not that it's around anymore, primary/secondary works perfectly. For electing something to control your distributed system "leader election" makes just as much sense as "master election". For git, "main" is 2 letters shorter than "master", and makes sense. All in all, this is good thing.
