StorageOptions.getService() javaDoc could be clearer

[lesv]

A customer has asked:
Storage storage = StorageOptions.getDefaultInstance().getService(); from storage quickstart

getService() is not defined.

Having looked at the JavaDocs, it could say that it returns a Service object for the current service, for example, if you are using Google Cloud Storage, it returns a Storage object. b/62208662

Just to be clear, is the issue that we lack a doc string here?

I think so. That's how I read the issue.
