Hi John,

Just in case: I meant to say that full table leaks are rare.

I do not oppose this draft - while I'm still not sure it will solve problem
of full table leaks, I like the concept, and I can see this proposal as
part of solution of general route leak problem.

But this brings next question: I hope that the meaning of "Import/Export
Policy was configured" is just *configured*, no matter by user or
automatically, am I right? (I'm trying to understand how it can stack with
BGP roles).
