An alternative, for the core document, is merely to note that
display of identity-related fields is a highly sensitive aspect of

Having the core document give ANY normative guidance on user
interface design and cognitive processing concerns -- note the
draft text says "should" -- or for that matter any guidance at all
is not going to help the focus or utility of the document's main
purpose.
This consideration depends heavily upon how the core document is
used. Not normally constraining associations between an email-
address and the signing-domain at the MTA, but instead assuming a
"recognized association" may be made at the MUA would be an example
of why this guidance could be problematic. I suspect a significant
constituency of users would desire such freedom, while also
appreciating improved protections.
