I found the draft to be easy to read, and it is ready with just one small issue: 

The 2119 boilerplate needs to be updated to include RFC 8174, and a normative reference to that RFC needs to be added. (I see the Doc Shepherd review also mentions this.) 

Nits: 

   s/ad-hoc/ad hoc

   Title of Section 5.2 should be headline capitalized. 

   There are a few places where there's a comma before "because". Those commas should be removed.

Thanks!
