In the seminal SF movie Tron (1982), MCP stood for "Master Control Program", and it has already been firmly established that "Master" is a problematic word we must expunge from our repositories.
No. Like "master" as a branch name, even if it's perfectly fine in this context, as long as it could be suggesting the word use in a problematic context, it should be banned. That's how we banned "master" as a branch name, so why not MCP?
Yes, I mean we should ban all abbrev with M in it /s
