How many kinds of indirect mail flows do rewrite From:?
Specific methods might prove more effective than general ones.

Since the receiver typically can't perform the same checks under the same
conditions that existed when the intermediary performed them (if it could, we
wouldn't need something like ARC) then the receiver has to decide if the
message is consistent with messages it's previously seen through direct mail
flows using that same authenticated identity that was captured by the
intermediary in the ARC header set.
Doesn't that assume some kind of omniscience at the receiver's? Consistency
with previous messages by the same source is not straightforward. Using the
same selector? Signing more or less the same set of header fields? Choice of
vocabulary? HTML vs. plain text style (e.g. line length)? A.I.?
