I think that this is really a process/RFC2026 process bug that maybe we could
find a way to slightly amend RFC2026 about. (How many gendispatches ago was
the 2026 revision discussion...?)
I think that we document cryptographic algorithms as Informational because it
is not the IETF's goal to take change control over the algorithm.
It's not that we don't think of them as Standards-Track, it's that our
standards track rules say that can't unless we have change control.
The IETF RFC, because it's accessibility, often become the defacto industry
reference. It is cited way beyond being cited in some other RFC.
Why doesn't the industry (and the IETF?) cite the original NIST,
etc. document? Well, historically, because the documents predate the WWW, we
had RFC-by-FTP-email, and NIST didn't.
My thoughts are:
a) create some new category which is pseudo-authoritative standards track,
which the IESG can annoit a document with.
b) cite the original documents/papers/NIST-etc. publications more often.
Perhaps CFRG has already struggled with this question before.
At this point, what I see is that there is significant original work being
brought to the CFRG *first*, that a CFRG RFC is becoming authoritative for
some algorithms. (No, I don't have an example.)
