It sounds way less offensive to those who decry the original terminology’s problematic roots but still keeps its meaning intact.
I look at “master” in our repo like you would refer to a master recording or a remaster, or similarly the gold master for when you could say a video game has gone gold.
I don’t know what a master recording is. Googled it and it seems to be related to vinyl or something. So yeah, kind of hard for me to wrap my head around that, but definitely an interesting outlook.
