WH> My position remains that RFC8663 is a valid alternative and is available; I 
am against WG adoption of CRH.


The industry widely supports RFC8663.



Instead of denying the evidence, could the CRH authors and proponents finally 
understand that people are not opposed to new ideas?



People are reminding a long-standing practice of the IETF process. Before 
tackling a new piece of work, a working group must perform a due diligence on

  1.  whether this new work is redundant with respect to existing IETF 
protocols,
  2.  whether this new work would deliver genuine benefits and use-cases.



It is factually and logically clear to the working-group that the currently 
submitted CRH documents.

  1.  fail to position CRH with respect to existing standard widely supported 
by the industry (e.g., RFC8663)
  2.  fail to isolate new benefit or use-case [1]



This positive collaborative feedback was already given in SPRING.

The CRH authors may change this analysis. They need to document 1 and 2.



Why did the CRH authors not leverage this guidance in SPRING WG?

This was also the chair's guidance in Montreal [2] and Singapore [3]



All the lengthy discussions and debates on the mailing list could be avoided if 
only the CRH authors would tackle 1 and 2.



The CRH authors must tackle 1 and 2.



  *   This is the best way to justify a/the work from the IETF community and b/ 
the hardware and software investment from vendors.
  *   True benefits must be present to justify such a significant engineering 
investment (new data-pane, new control-plane).



Thanks
