As specified in the registry, allocations in this registry are either by
IETF Concensus (i.e. a suitable RFC such as this draft is intended to
be) or request from a RIR. Thus it isn't a matter of suggesting to IANA
but telling them what the IETF want done - so this draft should be
definitive - and what you said about WG concensus constitutes the values
to be used unless somebody else in the IETF manages to alter the
concensus which seems unlikely.

Yes, that's fine and as expected.

Publishing a separate draft seems a bit overkill but clearly that's not
my decision. ;-)

This document would be an opportunity to explicitly mention that the topmost value is reserved (for future expansion? :-) )
