Same here. FWIW, I'm manually setting PL to 15' and VL to 30' as a way 
to cope with flash renumbering events.

In any case, when so many things need to happen and work in a certain 
way for the network to be usable, that's arguing for broken design.

And that doesn't seem to align well with the goal that "the network 
works as long as there's a working path between source and destination".
