I think it should be decided whether we want extra levels or not, and
apply that policy to both the C and Rust sides.

If we don't, then yeah, let's remove them in both sides and just let
users modify `CFLAGS` as needed.

If we do, then having them as config options makes sense so that they
can be kept working.

Cheers,
