Arnt, can you elaborate on why you think the reason is not sufficient?
Sorry. I should have done so in the first place. If I had tried to formulate my intuitive thoughts I would have ended up with a something like: "Editheader SHOULD NOT allow removing Auto-Submitted, because it's known to be used for loop prevention. Disturbing someone's loop prevention logic is both rude and harmful."
Editheader shouldn't be courteous to mailto-notify because both are sieve systems. It should be courteous to everyone because mail loops are $#@!$#$!@ painful.
