Hi Tony,

well said.

With this in mind I'd rather ask: Do we really need SID list compression 
at all?

If silicon sooner or later get's tailored for SRv6, can't it be made to 
simply parse big enough headers?

IMHO SRv6 is the one thing that really allows for full flexibility for 
whatever use-cases may come up in the future. Any compression scheme has 

Best regards, Martin
