Hosts API returning more that one instance of lifecycle environment - which one to use?

When querying a host via the API, we get different fields representing the hosts lifecycle environment:


So it is returning the same information once as a structured hash and once in seperate simple fields.
Is one of these fields deprecated or are they just there to “use what you want”?
