The problem is that the warning should only be for headers that are not installed yet, but it needs to be stripped in the installed version. Since we're already postprocessing all files with unifdef, that seemed like the easiest way to strip out the #warning. Obviously, I couldn't use the #ifdef __KERNEL__ logic, because that would either warn give false positives when building kernel code or when building user code from installed headers.
