That's a good thought. Indeed if there is a bad signature on a message
it just tells you that the man-in-the-middle was too dumb to remove the
whole signature if he changed it.

I fully agree that the trust value of a message with bad signature, a
message with "untrusted good signature" and a message without signature
are equal.
