You set things up so you can't disable -Werror on the build server, and all this is moot.
The point about alternative implementations is interesting. Java has a comparable situation with unreachable code; the language specification has a simplistic definition of what unreachable code is, and makes it a compile-time error. A smart compiler can find more cases of unreachable code, but isn't allowed to make them errors. So it makes them warnings. It doesn't seem to be a big impediment to alternative implementations in practice.
