Negotiation can mean that A and B receive different messages, both stating
(in to/cc) that the other received the one they didn't. Sounds very fishy
to my ears.
This is nothing new; situations arise routinely where the header recipient
lists don't tell the full story about who did or did not get a message
Agreed. It's nothing new -- just more of a bad thing.
I suppose it's okay, though. If to/cc never were truly reliable, making
them even less reliable is no big deal. Even if it's the first time a

or a

Hm? I know that some mailing lists do rather a lot of header field
rewriting and/or append a new signature. Are there other examples?
Sure. There's plenty of content conversion/charset
conversion/reformatting/virus removal, etc. etc. etc. going on out there
already.
