Not sure if this is a feature or a bug. Brian/Vladimir, do you recall whether Node Modified notifications were specifically suppressed during state transfer, and if so, why?

There was a reason we did not go through interceptor chain; I remember it well; but what it was - kill me - I cannot recall.

I'm sure this is discussed on a thread if someone wants to search. :) I'm lazy so I'll just guess about the reason. Going through the interceptor chain adds all sorts of possibly unwanted side effects; e.g. creation of in-memory nodes cause writes to persistent store, replication, gravitation, etc. Many can be eliminated by setting options, but thinking through all the ways it can break will take a lot of work and it will inherently be fragile. Manik's right though; my question was about the Node Modified bit. :)
