What about adding a checkbox in the mailman profile for subscribers of the
lists that basically says: if you detect that the sender is using DMARC then
please rewrite the From header.
There is already code in Mailman, e.g. if not
(msgdata.get('from_is_list') ... to do the above. The configuration
can be set by AMS.
People who receive the list on a yahoo account would have to mark the checkbox
(though maybe a list of default domains can be hacked in such that new
subscribers for those domain would get it set automatically)
The focus has been on Yahoo because of a message which was posted
several years ago. I collected some statistics for an IETF mailing
list. Approximately 40% of the subscribers are using [1] DMARC; most
of then are not using Yahoo.

1. This is not the percentage of subscribers using "p=reject".
