Should issues be raised on GitHub for resources that are missing in the

google-native

package? I wasn't sure if the fact that it's in preview means "we're still adding all of the resources" or "all of the resources are there and we're just battle-testing things now"

Yes, please, if it doesn’t exist yet. We added all the resources that our current approach could find. Some resources have unusual setup of API methods and we may miss them. Also, some specs are missing from Google discovery docs - we can raise that with Google.
