Summary: Ready with minor issues.  (It was fun to read this I-D, lots of historical context.  Thanks for putting it together!)

Major issues: 0

Minor issues: 4

Nits/editorial comments: 2

Minor:
- Global
 - I am surprised that the term "Round robin DNS" is not defined in this
  document.  Is it worth defining?  It is used quite a bit.

- S2, in the definition of "Global DNS", second paragraph: In the last
sentence of the paragraph, you use "octet" and "byte" interchangably.
Perhaps stick to octets as we are talking about a collection of eight
bits on the wire.

- S5, in the definition of EDNS, the text says, "...to indicate the version
 number."  Is there a EDNS(1) (or EDNS1)?  I don't believe so, but it has
 been a while since I was caught up on latest work in DNS.  AFAIK, it has
 always been called EDNS0, from back in rfc2671,  RFC6891 continued with
 EDNS0 instead of EDNS1.  Is it worth to provide historical perspective
 and say that till now, the version number has not changed since rfc2671?

- S6, RDoT and ADoT: I do not believe that rfc7858 definies these terms.
 Is it worth referencing where these terms originated from?

Nits
- S2, right above "Private DNS:", please expand PTI on first use.

- S3, in the definition of QNAME,
  s/this creates kind of confusion/this creates confusion/
  ("kind of" is okay for colloquial use, but not in standards documents.)
