since this doesn't define a new domain name (it uses a
domain literal), there's no need to update BCP 32.
Sure, but you want this idea to replace the "best common
practice" From: <what(_at_)ever(_dot_)invalid> based on BCP 32, and
therefore the best place to document it is an updated BCP.
It's important that user agents support these conventions,
and don't offer to send mail replies to invalid addresses.
That was the point of Bruce's draft, and that's also the
reason why Usefor drafts proposed TLD .invalid for about
five years.
