Yeah, introducing a new field and deprecating the old one seems like the best option here. The nice thing is that while this introduces new functionality, there's still only one version of the server; if you query for `homePlanet`, you always get the name, if you query for `homePlanetDetails`, you always get the planet object. This is particularly useful for tooling, since the API response is a function only of the access token and the query.
