I believe this has been in a bit stall for some time. I'm finally
trying push for some real production implementations.

I have one note that I wrote when I was initially reading the draft:

- Canonical RR Form comes from RFC 4034 s. 6.2 and it doesn't require
require normalization of SPF and CAA records. RFC 6844 specifically
allows any string formatting allowed by
https://tools.ietf.org/html/rfc1035#section-5.1

Not sure if there is any real issue with this one but in theory I
guess there could be functionally equivalent records with a digest
mismatch. Maybe it's even desirable that those are not normalized,
just a note.
