Well, last time i measured it was a lot slower. I would think that
a good procedure was that if someone wants to remove healthy code
that he has to proof that it is valid to do so.

Please test at least the cases that /etc/rc.firewall allows for
and provide a script like it for replacement.
If you can't even test that, you shouldn't be allowed to remove that code.
