Not overrated or impossible. It's part of our business model. It works.

Better if the database driver you are using supports it... otherwise 
userless
I think there is a need to drive towards some sort of standard approach 
to this in DB-API (maybe version 3?) as it otherwise nullifies 
parameters for anyone using multiple database drivers.
