Yes, I'm sure it is.  The requested number was not added to the draft,
because it was too late to do so before publication.  A few days later,
Bill Sommerfeld, who was WG chair at the time, posted the following:

That remains the case today.  The registration policy for that registry
is "IETF Consensus", which means that getting a new number assigned
requires publishing an RFC.  For this sort of thing, that could happen
relatively quickly, once someone writes an internet-draft.
