How do you determine that an evaluator is enforcing DMARC "against lists"?
That assumes there are lists that don't munge From:. Is that real today?
How can one definitively identify list traffic?
Certainly not by List-* headers. In particular, List-Unsubscribe: seems to be
required in most mail messages.
Also, I imagine that if munging is to be considered reversible, either the
munging itself, or a way to describe it, needs to be standardized in some
form.
Hasn't that ship sailed already?
