Many thanks to the DT for the good and thorough work(1)!

And many thanks to Wim for bringing this thread to the list.

My view as an operator is:
We already have more than enough standards and options. Often enough 
actually introducing new technology in a multi-vendor environment is a 
pain because not all vendors implement the same option at the same time, 
and rather have different understandings of the overall architecture and 
of priorities.
Thus I'd really suggest do proceeed with just a single solution.

If I got it right, one vendor and one operator intend to continue with 
CRH independently of segment routing. That is of course perfectly 
legitimate. From my perspective it's still a pity because we won't pull 
together. And the vendor will - from my perspective - waste development 
energy on technology that will never be useful for my enviroment.

Best regards,
Martin

P.S.:
(1) The requirement I suggested in April, concerning Number Resource 
Management, apparently didn't make it into the documents. But if I get 
it right, the overall reesults wouldn't have changed.
