Dear All,

I don't support the adoption.

>From my point of view, CRH is not providing any advantage with respect to
SR (that is a mature technology now). Regarding header compression, several
solutions have been proposed for SRv6. Moreover, the SFC support is not
provided in CRH (NSH is needed). Finally, I believe that a detailed
comparison between CRH and SR is needed before proceeding with an adoption

Kind regards,
