In fairness, they exist by virtue of having working implementations that (at least a few) people actually use, not by virtue of being an Internet-Draft.

SCEP was (and still is) a very deployed protocol yet took 20 years for the draft to be published...

It is not an individual I-D, but has been adopted by a working group, and has a chance of actually being published as a RFC.

they are disgustingly slow so maybe we need a new draft...
