Re: [IPv6] Adoption call for draft-bonica-6man-comp-rtg-hdr

Hi 6man WG:

I think the document should have more discussions on Security aspects.

SRv6/RFC8986/RFC8754 has built the security of an IPv6-based trusted domain (SR domain) on the highly strict IPv6 address management.

To define a "IPv6 address block" for special-usage (the so called Network-Programming), is a solid paradigm to make such an IPv6-based trusted domain IMO. 

In my understanding, once there is a need to use a "special-usage" address (which differs the RFC4291 address), no matter GUA/LUA, the management of such address should be built on SRv6 NP (not bounding to an Interface/Loopback, and populating FIB differently, etc).

The removal of reference to SRv6/8754/8986 will make this solid paradigm no longer to be useful. I see there are challenges faced, for example:
CE1----PE1[Provider-network]PE2----CE2
CE1 may want to use a SRv6 SRH with an active SID being a PE's SID under a VRF context, and the last SID being the CE2.  
With this document, the case will not able to be supported I think.
See a draft (expired though) https://www.ietf.org/archive/id/draft-xie-spring-srv6-npi-for-overlay-00.html.
Another similar example (VPN-CAR case ) https://datatracker.ietf.org/doc/draft-ietf-idr-bgp-car/

Thanks,
Jingrong
