Personally I think this is a mistake. As we all know, English words have context, the meaning is adaptive depending on the situation. "master" branch has precedent, we have trained our brains to think about "rebasing onto master". This small change will be disruptive, forcing us to unlearn existing, common phrases. Whitelist & blacklist I support discontinuing, however master is a homonym so doesn't have the same obvious connotations.
