I think repository notifications have been a huge win. Obviously we  
use them too much -- especially in the calendar, which we should (and  
can easily) improve. However, I think getting rid of them is a mistake.

I think it isn't obvious that object relational mapping is faster  
than persisting whole objects. If you don't believe me on this point  
go spend some time Googling the subject.
