The fact that it comes up every now and again on this list and creates
a thread of discussion eight miles long ...
But that's not even important, I'm not asking anyone to _do_ it, I'm
asking why, every time this topic comes up, it provokes such a long,
painful thread of argument.

Since when am I asking for security through obscurity? I'm not telling
you to move ssh to an unusual port in the hopes that nobody will notice
that your root password is "password1".
What I'm _asking_ is why would extending SECURITY DEFINER to include
preventing unauthorized users from viewing code _not_ be a valid method
of securing the code. Whether or not enough people want it to justify
the manpower to do it is a different discussion altogether.
