If you mean that one should not be able to change them above a certain
securelevel, I'm not so sure. After all, it's production machines
that are most likely to be running at a higher securelevel, and it's
production machines that are most likely to need this facility, since
if you could reproduce the bug on a development machine with a non-suid
version of the binary, you would hardly be likely to be trying to debug
on a production machine.

What advantages do you see to making it depend on kern.securelevel? What
threat model do you have here?
