Indeed, and not creating the problem is good thing. I don't think we are
disagreeing on anything here ...
Although I don't believe anyone has mentioned "multi-topology" +
"transition" just yet, the goal being that when you go from ST to MT
(assuming you aren't already there, that is) you don't impact ongoing
operations / neighborships.
