One might note that the same kind of difficult debate over 'error handling' has been at the root of much controversy in HTML land.



Don't many MTAs actually implement the same "sniffing" for content-type and charset as is being proposed in

It was my impression they did.



Is "wrong content-type" a "malformed message"?

It's meant only as a starting point.  And I think extending it, if done carefully, will produce something readable and valuable.

"...and what the consensus view is about what to do with them," precisely.
