Yeah, I agree actually. That was an experiment in the radical
simplification. I'll have uniqueKey, and _version_ back. But the fact
that the schema still works is a good teaching point, in my mind.

At the same time, I am still struggling with the reasonable minimal
solrconfig.xml. None of the shipped examples are reasonable, because
they all include - as a data point - enableRemoteStreaming=true ....
So, something has to go. But what has to stay is unclear. Perhaps
that's something to discuss at the meetup.
