[spring] Re: Call for adoption: draft-ali-spring-srv6-policy-sid-list-optimization-01 (Ends 2025-11-19)

Hi WG,

I support this adoption.

The SID list can be optimized by excluding the endpoint Node SID when
installing the policy.
It can significantly improve the forwarding performance of the egress node.

Thanks,
Allan
