You seem to be missing the point I was trying to make.

We're talking about IPv6 routers doing heavy surgery on IPv6 packets, 
while en-route to destination.

And we are also talking about violating IETF specs at will, and 
circumventing IETF processes.

This does break things, make troubleshooting painful, etc.

AH may break
PMTUD may break
Error may reporting break


I'm not being purist. I'm just arguing that we probably can do better 
than simply rubber-stamping any hacks a vendor with big pockets may 
bring up.

Otherwise, I don't see the point of all this big structure.

For instance, we have an "Internet Architecture Board", which I guess 
have a say on things that affect architecture?

Thanks,
