It is just a matter of some additional bookkeeping to track the last
seq that changed the view. That would help with the Etags a bit. It
isn't quite as good as etags that reflect the last update sequence
within the query range. Those would be possible as well, but would
require running a reduce calculation to generate the etag, which may
or may not be worth it.
