There's a difference between "legitimate" and "useful". If the top comment on every CockroachDB post was "hey y'all remember that Go's maps aren't thread-safe", that would certainly be a legitimate warning. But at the same time, the CockroachDB team have been coding in Go for years, and they obviously already know that. If those top comments frequently turn into big threads arguing about whether Go's maps should have been thread-safe, the whole thing goes from being questionably useful to seriously annoying. Same thing's happening with the name. They know.
