I think that would be a nice addition. It would implicitly allow a
recipient to reject a message when it knows some fields are not
properly formatted, before recombining them. Your example with a
single double-quote could serve as an encouragement for some
intermediaries which want to be strict to systematically reject
such individual values early.
