The point is that the network infrastructure vendors will not invest a lot of 
time and resources, at least not given the current state of affairs, in trying 
to tie their network infrastructure gear into any kind of delegation 
certification PKI infrastructure, as most of the gear they sell isn't connected 
to the Internet and hasn't any way to connect to the putative delegation PKI 
system.

Another point is that, given the various controversies in the 'classic' DNS 
space with regards to various domain takedowns for reasons other than 
straightforward abuse, the benefits of such a system vs. its potential 
susceptibility to legislative and regulatory incursions isn't a settled issue 
(the same concerns apply in the routing space, as well as with regards to 
DNSSEC).
