Any attempt by senders to filter outbound emails based solely on content is

I find the idea of using different, probably less stringent, filtering on
outbound than on inbound to be hypocritical.
You have much more data for inbound email, and access to a much wider range of
reactions. That’s not “hypocritical”.
The only information a sender has that a receiver doesn’t is a broader view of
who the recipients of messages being sent are - and that’s exactly the
information that DKIM replay hides from the sender.
Large sites should exchange reputation information on each other's accounts.
Murray already proposed a standard for doing so.
