Is that wise? We risk adding a syscall to an architecture without the
arch maintainers and testers even knowing about it.

The compile-time nag is there to inform the arch maintainers that a new
syscall is available and that they should wire it up, run the selftest
and then ship the code if they're happy with the result.
