I actually worked in film audio engineering and Master is not the universally used term and hasn't been used uniformly throughout history. I have an analog Mackie mixer from the 2000s with "Main" as the name of the Main Bus that was designed before the whole debate took part. As far as software goes, things are similar. The process of "Mastering" is an exception. As far as git branches go, I am fine with main. It has two advantages over master aside from any culturual questions: 1. main is more self-explanatory for beginners who don't know how "master" was/is used in tech. 2. it is shorter. While two letters don't make a huge difference, that is still a subtile advantage. Whether these two points alone are enough to justify the needed work (which is probably not a lot to be honest), IDK.
