A bit of a problem I see is that there is still no support for plugin data providers. Are you thinking about implementing this as a plugin layer?

Yeah it is pretty cool.  That is where I first got the idea from.

My main idea was to have a QGIS implementation of that that can sit on
top of any QGIS layer not just OGR ones.  So instead of having a
backend of OGRFeature and OGRDatasource it would use QgsDataProvider
and QgsFeature.

It's pretty cool that there is a Python way to do this, will be good
to prototype something quick then port to C++ for speed.  I might have
some time tomorrow to try my hand at something basic and if it works
we can explore it further.
