-----Original Message-----
From: ipv6 <ipv6-bounces@ietf.org> On Behalf Of Tom Herbert

> Right, SRH is an extension header that works with the existing
extensibility constructs for IPv6. Fundamentally, I don't understand
what problem a new encoding would address, perhaps you could
articulate that (personally, I wouldn't consider a use case where only
one bit of extensible information is needed as justification to create
a new version of IP).

This topic seems to be similar to the one about giving semantic meaning to IP addresses. If the standards say no, and that's what they say, then anything like that would be restricted to "behind closed doors, among consenting adults."

Not sure how anything else can work, with the standards as written, and as widely implemented, for many years.

And if the implementation is non-standard, in limited domains, it could even be seen as a "feature," in that limited domain.
