No.  That misses the point entirely.  The problem here is that one can take a
DKIM signed message that is signed by any entity and add additional
From/Subjects and the message may still appear to be the one signed by the
original entity even though it's been modified post-signature.

Right. I had understood that and then forgot.

If DKIM is just viewed as providing an identifier and nothing more,
then this is a MUA problem.

If DKIM is viewed as providing more than an identifier, then this is a
DKIM problem.
