I've had a quick look at the diff, and some areas I felt I should look
at again. I'm generally very happy about the outcome. Thank you for your
hard work. Some minor comments:

Sections 3.2.2 and 3.3.2 say «Certain characters from the Exceptions
("F")». That's a bit awkward as a reader. A forward reference to section
7.6, noting they are explicitly listed there would help.

In Section 4.1.3 about case mapping we currently have:
«In general, the combination of case preservation and case-insensitive
comparison of internationalized strings is NOT RECOMMENDED; instead,
application protocols SHOULD either (a) not preserve case but perform
case-insensitive comparison or (b) preserve case but perform
case-sensitive comparison.»
I wonder what the rational for this is? Both SASLprep-bis and Nicknames
seem to want case-preservation, but case-insensitive comparison. I may
be mistaken though.

In Section 10.5 "Visually Similar Characters" I'd suggest a reference to
UTS #39, describing confusable detection and mixed-script detection.
