Hey, you're the guy who took out the special variable. ;-)

I agree with your new position--it's more useful to be able to change
the behavior of a running server to choose between logging, ignoring,
or debugging errors just by setting a variable. Whether it's in a slot
or special variable doesn't matter a ton. Though I could imagine cases
where a special variable would be handy--you could change the policy
in one piece of application code without affecting others.
