p=quarantine is quite useful, particularly for those folks who are trying to get to a p=reject state. 

In practice, senders who publish p=none don’t find all of the indirect mail flows as some mailing lists do nothing to transform the 5322.from address for a p=none policy. Senders have found that when they switch from p=none to p=quarantine pct=0 they regularly find mail that was not failing for a p=none. 

p=quarantine should stay in, especially if the goal is to encourage senders to publish a p=reject. It’s a valuable step in the deployment process.
