Result Has nits
Completed 2019-09-10
This document looks mostly good to go. I only have a few questions and some
various editorial nits.

- Section 4, last paragraph: Will code points "considered unsafe" be labelled
as such, and if so, where? In the derived property IANA tables? (Assuming those
tables are kept.) - Section 5, second paragraph: How will the success of this
document's proposed changes be measured in order to determine if further steps
towards minimizing confusion are needed?

- Section 2, first paragraph, first sentence: It seems a comma is missing after
[RFC3491] reference, i.e., "..., commonly known as "IDNA2003" [RFC3490]
[RFC3491], ...". - Section 3, second paragraph: s/full Unicode versions/major
Unicode versions? - Section 3.1: s/also concluded that maintain Unicode/also
concluded that Unicode? - Section 4, third paragraph: Is the requirement that
changes which are "documented" redundant with the following "explained"
requirement? (That is, perhaps just say "... must be documented and explained."
- Security Considerations, second paragraph: Do "end users" include systems
that process or interpret Unicode values? If not, it might help to specifically
call them out, as problems may arise from misinterpretation there.
