Those are a weird choice too IMO.  I think we inherited that without much review from the downstream, but I kind of want to push back.  The `-is` doesn't really buy us anything here.  I'd accept the flag as an alias, though I'm not sure how much value there is as we aren't really functional in the upstream, so our users are limited.
