Keeping in mind that mailing lists have been a legitimate Arpanet/Internet email activity since the start of network email and that it is DMARC that created operational problems, rather than mailing list activity creating problems,  the onus for declaring a nearly 50 year activity no longer supported should be pretty compelling.  It should not rely on anecdotes or the views of an isolated few. And it certainly should not justify the change with some broad, cavalier claims about security.

For starters:

 * Please document attacks and other misbehaviors that have been
   attributed to mailing list operation
 * Please provide objective, validated documentation for you assertion
   that the traffic through mailing lists is tiny.
 * Please include similar substantiation for the percentage claim
 * Please explain how this type of long-standing legitimate activity
   can reasonably be otherwise conducted; a generic reference to the
   web is not sufficient; what is needed is a point-for-point
   evaluation of mailing list group and technical functionality and an
   comparison to replacement choices.

Once these documentation details have been lined up and have obtained meaningful community support, it might be worth pursuing the de-legitimization of Internet mailing lists.
