With NoSQL picking up craze, postgre gaining popularity and WordPress moving
towards being a complete CMS, its a move that we should make.
Propel might be a good option, may be DAOs.
But this option is good for progress of the CMS as a whole.
I bet people will start discovering new areas for improvement within the
core as they implement database abstraction.
