the explanation suggests that the '99 numbers _may_ be assigned in the
future. With the 4-digit RFC number space due to expire before 2020,
there are now some serious issues around number conservation and re-assignment.
This goes beyond the '99 series but relates to other unassigned numbers, as well.
Of these unassigned numbers, there are at least two kinds: 79 RFCs (ending with
RFC 4637) are explicitly marked "Not Issued.". Of the RFC numbers below 7000,
94 have not yet been assigned -- in addition to those marked "Not Issued.". (*)
The latter category includes '00 and '99 vacancies and includes numbers
before 4637 (marking the end of the "Not Issued." era) and after
(NB: 4637 is the elder of a pair of twin primes).
I would like to suggest some research be conducted on the number exhaustion
problem to inform a debate about the future use of unissued numbers of either kind.
