Short-circuit evaluation should either be a MUST or a MAY.  It needs to be
mentioned, so people know whether or not they can rely on it when writing
code.

Yup.

I'm not sure.  How does this interact with the local-part being
case-sensitive and the domain-part being case-insensitive?  Could it lead
to confusion?

Sounds reasonable.

I could live with this.  A lighter-weight alternative would be:
Implementations are required to (a) treat all non-ASCII characters in a
script as a syntax error or (b) decode MIME header encoding.  That's the
"you don't have to do it, but if you do it, do it right" approach.

Why is that a bug?  Header names are US-ASCII case insensitive in RFC 822.
