We now have https://issues.apache.org/jira/browse/SOLR-8220
"Read field from docValues for non stored fields"
And there is an issue open for how to optimize for cases when fields
have both docValues and are stored.

Then the other missing optimization is to use a more efficient sort
(and possibly defer sorting until streaming) when dealing with an
entire result set.
