What I've seen personally is the rename started with the terminology of "master/slave" such as for database replication. This is happening now and at speed because of Black Live Matter and related progressive movements. My clients are changing terminology from "master/slave" to "main/replica", and from there it's an easy step to changing terminology from "master" to "main" everywhere else including git. My clients are doing related kinds of word changes, such as changing security terminology from colors "white/black" to functions "select/reject", and "whitelist/blacklist" to "allow/deny", and "white-hat/black-hat" to "ethical/criminal", etc.
