That still seems pretty reasonable. They want ".new" to be seen and used as an interaction element, not as a random TLD. E.g. if twitter would get one, twitter.new would bring you somewhere where you could directly start typing a new tweet.
Well, good luck when your app gets flag by their bot, broken because the .new no longer works, and you can't get a hold of Google to remove you from their blacklist.
Just read all the horror stories about apps on Google Play.
tesla.new where you can order directly online, yeh probably. That's I reckon exactly the kind of distinction I think they're going for. ford.new would make me go to a dealer so I think they should be able to never get one.
As a user I don't think I'd ever go to .new directly. If you've got some other way to get users there from the main site, you might as well use a query string, path, subdomain or some combination of the three.
I'm not a web dev, but I've dabbled a bit over the years. So I guess I could be missing something. I'm sure the right marketing could make this work.
