As was said in earlier quips, Chandler was designed with an infinitely 
scalable and infinitely fast repository in mind. It seems to me that the 
application layer needs to be "messed with" to no longer work with that 
assumption. No amount of relational model is infinitely scalable or fast 
either. If the app keeps its current frivolous repository use patterns - the 
SideBar collections come to mind - the new model, whatever it is, is not going 
to fare well. This includes a "newish" model where we add a mapping layer 
between the existing repository and the app layer.

I'm all for adding such mapping layers giving us better nimbleness in tuning 
or trying various implementation approaches, but these are not infinitely 
scalable nor fast either.
