It's just a case of calling ships from the Federation Federation ships. Anything else, as I said before, is just splitting hairs or quibbling over terms.
Not really. If a ship isn't registered to the Federation it isn't a Federation ship. Even if for some reason that did not seem like a substantive difference, it does matter to the issue at hand, which is ship naming conventions. There have been HMS and USS Enterprises in simultaneous service for decades. To an alien, they can both be colloquially called Earth ships, but they can both be called Enterprise as they are not registered into or part of the same Fleet.
