If you want to work on this, go ahead.

Notifiers are nicely decoupled, so you should be able to define more and
use them without much trouble. For example for object changes that
affect the data indeed one or more ND_* types need to be added for

However there is the issue of how to do things like preview render
updates, clearing display lists, etc. I think we have to use blenkernel/
functions for that, and avoid using editors/ functions in RNA code, only
interacting through notifiers there if possible. How that interaction
will work is a bit unsure still though I imagine with proper use of
notifiers and DAG_* functions you should be able to get quite far.
