Are you proposing that an entity always be the owner of something?
If so, I dislike using the term "entity", since entity does not imply
ownership. I'd prefer "owner" or "account", since the latter implies
control over something. Entity connotes neither ownership nor control.
I'd like to get the semantics around these terms correct. We've
already run into numerous issues with the term "metadata" and I really
don't feel like introducing another source of confusion in both the
documentation and the code comments.
