Its not at all clear to me that such compression state belongs in 
TCP/UDP/SCTP
rather than being inside IP.  In practice, any IPv6 host has some amount
of IPv6 protocol state.  That is probably the right place for this 
information.

That might well be reasonable.  One would want to see the details before
drawing a firm conclusion, of course.

In my book, "reasonably strong binding" means some form of cryptographic
authentication.
