Your response is to generate many useless efforts to clean up the IETF specs instead of just doing what everyone else does, which is to ask a question, find the answer, and move on. It feels like you are wasting lots of people's time for the benefit of no one other than maybe yourself. (If there are others who feel that Mykyta's efforts are worth our time, by all means speak up and I'm happy to back down here.)

The 'afs' URI scheme may not be classified as Permanent, because of the lack of what mentioned in Section 2.1, 2.3, 2.4, 2.6 and 2.7 of RFC 4395.  This scheme is not appropriate for Provisional because of the points described in Section 3 of this document, especially the cited below:

I think the exact category these schemes are recorded under is not the key issue here.

These schemes were registered because it was believed they would be used but no-one has actually used them.

What is the real value and benefit in doing all the work to move them to historic? No one uses them so no one benefits from tweaking the category they are placed in IMO.

One could argue that it is good housekeeping etc. but given the effort to write a draft, have it reviewed and taken through the IESG to become an RFC that no-one will read (because no-one uses the scheme in the first place) just doesn't seem a good use of the community's time and resources IMO.
