Review Comment:
Fair enough, I can update the admin guide. I don't want to mention
`diagnostics` in the property name. These are not really related to diagnostics
necessarily. That just happens to be the only mechanism by which we can expose
them currently. But in the future, I can imagine them being exposed via
Reporting Tasks and/or the UI, etc.
