Some things may not be as easy to do with a controller, but that doesn't mean features are going to be hacked out of the existing PC version so it would match a simplified console version; it means features need to be added for the controller, or extra UI elements or menus, to make it work.
Other companies use a nice euphemism for that: Streamlining.
