removeWildcardImports is a recent addition, and right now (and for the foreseeable future) it doesn't do what it says it does. It doesn't remove them, it just yells at you about it.

In my own projects, I have actually ended up having quite a few rules that just yell "don't do this", and with our new "regex lint" thing, those can be a lot nicer with line numbers and easy suppression. So the point of this PR is to do a little refactor towards the "forbid" word.
