exactly. don't plan to deploy what breaks things for the user edge. 

there are two issues here 

1/ what ISPs do that might break things at the edge

2/ what edge stuff is doing that will break things at the other end edge of a connection

It seems a bit odd that ISPs would actively plot to do 1/ whilst they could be making hard cash helping people at the edge avoid 2/

Odd because it adds a 3/ element which is stuff at the edge which will break stuff in the network. Do (some) operators see more money in a 1/2/3/ world?
