It seems to me that banning removal/addition of certain fields

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"?
sounds like a good idea. here's one use case though:
I've seen quite a bit of e-mail from Russian users who use Hotmail with
KOI8-R, but Hotmail tags it as ISO 8859-1. it would be useful to be
able to correct the Content-type header here, both to get correct
BODY-matching and to let the MUA view the e-mail properly.
I can't think of use cases for the other headers.
