The point of my proposal was to make an option per subscriber.
Ok.
The most sane way to deal with systems that reject or otherwise discard mail
that fails DMARC checks is to rewrite the From.
Ok.
So the only sensible way forward is to have a per subscriber option.
A per-subscriber option makes matters easier.
So is that one mailing list typical, or just a bunch of people who like to
reject mail?
Alexey posted some statistics about all the IETF mailing lists at
https://www.ietf.org/mail-archive/web/ietf/current/msg100242.html
That one mailing list is not typical. I don't have access to the
data at the SMTP level to comment about messages from the mailing
list which are rejected by receiving mail servers.
But apart from that, you are saying that for at least that one list, if
you send a mail to the list with a 'p=reject' then 40% of the subscribers are
not going to see that message.
No. I am saying that 40% of the subscribers are receiving messages
from the mailing list through mail systems which advertise DMARC
policies for the domain names which those subscribers are using.
