According to [configuration](https://github.com/FriendsOfSymfony/FOSOAuthServerBundle/blob/master/DependencyInjection/Configuration.php#L65), it should be possible to disable `authorize` key. But if I do, I get the following error: > You have requested a non-existent service "fos_oauth_server.authorize.form" I'm trying to migrate to Symfony 3.3, which disables forms by default, and I don't want forms & authorize neither (it's a private API).
