Another process question

["Wijnen, Bert (Bert)" <bwijnen@lucent.com>]

We've been doing Informational RFCs to document
why we reclassyfy some STD to Historic.

Do we also require that if a WG wants to make 
a PS (that has been there for many years) HISTORIC?
I understand we need to at least do a WG and then an
IETF Last Call... but it seems kind of busy-work
to also have to do an RFC to explain why...

The explanation is that it has only been implemented by
one vendor and that vendor's author is not sure they
still use it (he will check).

Thanks,
Bert
