Either way, until such time your solution is deployed widely enough to

Notable exception: DMARC. Broke email lists everywhere - including those that
folks use to solve problems on the net. Heck, it broke the ietf email list.
Indeed - while a self-inflicted injury on its customers, the network effects of
massive operating scale effectively transition the problem space from private
actor to public…
hence not an notable exception, but an actual example of "deployed widely
enough”
Hmmm.... But wasn't the initial impact of DMARC that so few senders of email
had implemented it?
If you (or your email service provider) deploy an optional solution (e.g. DMARC
p=reject) that prevents you from receiving email from mailing lists sending in
conformance with existing standards, then that’s your choice.
Expecting that others will automatically change their behavior (such as
wrapping email from mailing lists) isn’t reasonable - you’ve effectively
decided (or let your provider decide) that you don’t want existing
communications to work for some categories of standard-compliant email. The
alternative is ‘Internet Coordination’, but that requires actually coordination
before making major changes that will break things.
Also, the impact wasn't just on customers, but on trading partners &
communities - communications being a two way street and all.
One doesn’t communicate with folks who chose (or let their service provider
chose) not to receive email accordingly existing standards.
In any case, irrelevant to the dombox situation, unless/until someone actually
deploys at a scale large enough to require consideration.
Not relevant to the dombox approach - though, in fairness, haven't waded
into it deep enough to conclude that.
But re. "one doesn't communicate with folks .. etc." --- when one has
ongoing communication with a large group of people (e.g., an email list)
--- and a large provider shuts a door, the impact is on more than just
the customers of that provider
