That understanding is not necessarily correct. I hope that some
clever person will come up with a tweak to the proposed protocols
that avoids the need to bounce email with a non-ASCII sender (or
non-ASCII whatever).

RFC 6531 is about announcing SMTPUTF8 support in SMTP. That
is 1% of all the work that is needed to implement SMTPUTF8.
In order to announce SMTPUTF8 support, the other 99% must be done
first. To correctly processes SMTPUTF8 requires changes to address
manipulation, MIME support, delivery status notifications, delivery
agents (can't just blindly pass UTF8 into shell command lines),
and returning mail as undeliverable when the next MTA does not
announce SMTPUTF8 support.
The way I read your proposal is that Postfix would only pretend
that it supports SMTPUTF8, without doing the 99% of the work.
