​Well, my non-mail expert opinion for whatever it might be worth.

While the process of revising the RFC should have been followed, it does
seem that they are trying to solve a real problem.  Mail should come from
who it says it comes from, not make it trivial to pretend to be someone one
isn't.

So why not adopt a standard where the *sender* is always the list? The
obvious downside is that "reply to poster" stops working, but do these
"security" tools care if the reply-to is different from sender? if the list
default is "reply to poster" set the reply to as the original sender, but
"correctly" identify the message as coming from the mail server automation
... not the original sender.

Other than noncompliance to the existing RFC(s), what am I missing?
