Is it perhaps better to just say "editheader operations MUST NOT modify those four fields"?

This is definetely better. I've not seen those header fields ever being modified by intermediate MTAs (forwarders, mail lists, etc) nor is there any reason why they should by MDAs or their agents. The only thing is that Content-Transfer-Encoding may in theory be subject to changes if MDA wants to decode BASE64 into something more readable for MUAs (in theory it should not try though).

That's not relevant to the editheader extension.

The point is that if MDAs do it, so could SIEVE system to make it easier for other rules, but it really should not care about it and let other rules work with data that is in BASE64 same as if was clear text.
And I'm not entirely sure if that is actually mentioned or not.
