Ugh... this feels like a bit of the combinatorial explosion,
especially if we ever need to add another option. I wonder if it would
be possible to do something simple like just providing
"--include={schema|data|stats}" where you specify only what you want,
and leave out what you don't. At the risk of not providing as many
typing shortcuts, if the logic is simpler and more extensible for
future options...
