the problem is that you have yet to rigorously define it and how to

You referred to this incident as a "leak" in your message:

"a customer leaked a full table"

I was simply agreeing with you -- i.e., looked like a "leak", smelled 
like a "leak" - let's call it a leak.

I'm optimistic that all the good folks focusing on this in their day
jobs, and expressly funded and resourced to do so, will eventually
recognize what I'm calling "leaks" is part of the routing security 
problem.

Sure; I don't disagree, and I don't think that Randy does.  But just
because we can't solve the whole problem, does that mean we shouldn't
solve any of it?

As Randy said, we can't even try for a strong technical solution
until we have a definition that's better than "I know it when I see it".
