I think that won't happen. The use of p=none subdomains by various
entities that publish p=reject for their primary domain is intended for
addresses for their own staff to use in communicating via mailing lists
and perhaps other channels. If a freemail provider such as Yahoo would
be willing to create a lists.yahoo.com domain with p=none for use by
their freemail users, that domain would be subject to the same abuses
that caused them to publish p=reject in the first place.
