The correct policy is p=none.
Considering that mailing lists are only about 10% of legitimate email traffic and if your humans do not rely on mailing lists, then you will be fine with DMARC and humans.
Unfortunately, Franck is just wrong here. If you subscribe to a mailing list and publish a policy other than p=none, you will screw up the list for other subscribers.
I expect that out of self-defense lists will have to add patches to reject mail from anyone with DMARC policies.
