Is it your intent to submit a draft deprecating IPv6 Extension Headers?

I don’t think Fernando has argued the case that some EHs should be filtered in public transit networks?
In the whole I think it’s not a good idea that the IETF has some working groups working hard at defining new protocols and other working groups working hard at defining policies to block them.
For public transit networks, the IETF could work on describing ‘what is Internet access’. The production declaration if you like. And then regulation could be used to enforce that. We’d need encryption too I’m sure.
Now for EHs in general. Their functionality of providing a separate signalling channel independent of the application… it might be time that we accept that this was a bad idea. Which deployment status has confirmed.
Best regards,
Ole
