This is the best option really, it's the manager's job to correct behavior and there are lots of jobs out there where you don't have to deal with that.
Because I can't buy pizza.com but now I have a shot at pizza.new I guess. Some companies are willing to jump through hoops if it gets them a good domain
Yeah I get that, but rather than Google opening it up for open registration and having the usual domain land grab, they could have created domains for each action and allow service providers to register intents in their services for each action. It's going to make discovery of actions much harder if there are different actions for different providers. It will also mean the usefulness of the pattern will be limited based on the services I choose to use.
In your example - if I prefer Domino's to Pizza Hut, what do I go to? I need to go to pizza.new to discover that it's linked to Pizza Hut and then try to figure out what Domino's action might be. In the end I'll just end up going to the main site instead. I think the value of this concept is completely nullified by binding the actions/domains to specific providers.
