[development] Making blocks from some setting in Drupal 7?

My one concern here is that because the block system is push, not pull, 
all blocks in all regions are always generated, regardless of whether 
the page needs them. That means we run the risk of degrading performance 
by generating a whole bunch of material that we have no intention of 
displaying, unless we have some way for the theme to signal which 
regions it wishes to generate on any given template. And that's a tough 
thing to do in the current system.

This is one of the reasons I like the panels approach, but that's still 
pretty far from being able to fully emulate the block system.
