No other mailman list I use (or run) works like this.
It appears that at least lug.org.uk lists also work like this. On Fri, 17 Feb 2017, Brad Rogers via list wrote:
I'm not one of those responsible, but I can tell you why it's been done: DMARC issues with companies like aol, yahoo and so on.
Got it in one! On Fri, 17 Feb 2017, Paul Sutton via list wrote:
however on a note relating to yahoo it has apparently been hacked again. So if no one is using yahoo or aol surely we can go back to the previous settings and encourage people to use alternative services for e-mail.
The other side of the coin is that Yahoo! have been well involved in driving both standards and adoption of sender authentication methods over the years, and it's really not just them who have deployed DMARC.

It's a nice idea, but fails to take into account mailing lists.
Forwarding of emails by third parties (such as mailing lists and people who sell domains and do email forwarding) is certainly a challenge for sender authentication. It would be great if SRS was more widley adopted, but that will rewrite the envelope too. https://en.wikipedia.org/wiki/Sender_Rewriting_Scheme

The easy option would have been to do nothing and let deliverability issues happen.
