I've tested adding and removing custom language codes as a Rosetta admin, as an otherwise unprivileged project owner and as an unprivileged user, and it all worked fine. The only minor issue I've seen is that even if I am unprivileged I can access +custom-language-codes page, but there's no link to it, but that's totally not important at the moment.
