Here's a thought, although probably already known and just implied so
far. It seems that JNG's "tradition" was starting to be is the
payload-less option, where the client has to actively decide to get
extra info, instead of that info being sent to them automatically. How
about we have those three (or more?) options (payload-less, abstract,
and payload-inline) and force the client to ask for a certain one when
they subscribe? Payload-less would be the default. But this would keep
things simple, and allow all the functionality.
