Joel,
I agree with you that it is really hard and even impossible to determine
what is going on in the Internet regarding some technology, protocol,
etc. If we set the impossible criterion for the Historic documents,
this will really make very few sense. So, as I have been pointed out, I
find removing the regulation about 'out-of-use' technology at all quite
acceptable. Do you agree?
And as for the comment from Dave.

Declaration of historic needs to be based on affirmative data. The
declaration is actually only important to make for protocols that are
known to be problematic.
This is already covered by the 'deprecated' criteria in my draft.
All the best,
Mykyta Yevstifeyev
Issuing a declaration for mere non-use is a matter of convenience, not
need, IMO.

There are, in my opinion, two problems with Mr. Yevstifeyev's
assertion below that it is easy to determine when things are out of use.
The first point, to echo Andrew Sullivan, is that even if a protocol
is in use on the public Internet, it is not always easy to detect. It
may be used in only some portions of the net. It may be used inside
some other protocol that makies detection ahrder.
The second point is that enterprise uses and other private network

I bring to your attention RFC-4450, in which we made a bulk status
change of a bunch of PS to Historic precisely because we couldn't find
anyone using those protocols. However, such observations are
imprecise. For one, it is hard to observe what is going on on the
Internet, and those who do don't usually share their data (there is
some, but it is often regionally based, like the GINORMOUS store at
ETHZ). Another issue is that a protocol that is not detectable on the
Internet might be in use on private networks.
When we say 'out-of-use' we consider the usage of something in the
overall Internet. It is mostly not very difficault to find this out
via those people who take part in the IETF.
