And then developers can move to fastmail.fm; there are quite a few
mail providers, after all.  And I would expect market forces, combined
with mail providers who aren't trying to send official bills to
consumers that can be easily phished from the same domain as their
customers, such that there will probably be at least one mail provider
that will meet the need of developers and other people who need
traditional mailing lists as they have been implemented for decades.

Alternatively, hopefully ARC will become ready before this is an
issue.  At least a few of the major mail providers have said they
won't enable p=reject until ARC has had a chance to be deployed,
probably because they don't want to have a wholesale (or high profile)
defections from their mail service to providers such as fastmail.fm.
