My first comment is that the abstract is a single sentence, and I think that
each sentence can only have a single stress point, and the abstract has several.
(I was reading an article in AmSci:
https://www.americanscientist.org/article/writing-to-facilitate-reading which
alas, is not available, that explained much of this)

I think that the document is worth adopting.
Seems pretty short and seems like it ought to be easy.

Reading the document today, I don't quite understand what limitation the
dns-01 challenge experiences.  That's a wording issue with the
document, not a complaint that there isn't one.

  "This unique label creates an impediment limiting
   the number of other entities domain validation can be delegated to."

I'm not entirely sure why I would want to delegate the domain validation to
more than one entity.  That seems like a source of insecurity.
But, I seem to remember listening to a presentation at some point, and
nodding agreement.
