Okay, I can see it your way, and I reasoned out my biggest conerns.
I'm down to just one concern: We are already filtering in the modules using
"del" on dictionaries in the profile. It seems like we really want to do all
of our filtering in one place, so, do we move it all out of the modules into
the profile internal logic, or do we keep it all where it is?
