For the offending paragraph in section 1.4 of the IDNA Rationale,
how about just deleting all the cutesiness and going with
something *very* straightforward:

IDNA uses the Unicode character repertoire, for continuity
with IDNA2003.

That is more appropriate, IMO, in the rationale document,
than allusions to April 1 RFC's or any statements, positive
or negative about how one judges the status of Unicode as
a standard.
