Hmm, even if the scripts replaces the Message-Id header ;-)?
It seems to me that banning removal/addition of certain fields
simplifies life a lot without removing significant benefit: Message-ID,
Content-Type, Content-Transfer-Encoding and MIME-Version.
Modifying those four fields adds so many corner cases to the
implementations. Do we have to go there? Is it perhaps better to just
say "editheader operations MUST NOT modify those four fields"?
(Solving a difficult problem gives a certain satisfaction. But avoiding
it can be good, too.)
