I think section 5 is roughly equivalent to
draft-ietf-curdle-des-des-des-die-die-die (of which I am coauthor),
which is currently waiting for the IESG to decide whether it is more
appropriate to move RFC 4757 to Historic or make it Obsolete.
So I'm surpirsed that this draft did not refer to "RFC xxxx" in
section 5 but did refer to it in other places :)

I think it is worth having this WG do the work it can do in this
space within its charter (which is probably the bits in this
document minus sections 3 and 5).  It feels a little strange to me
to do it all in a single document, as this does, but I wouldn't let
that stop us from doing it.
