IIRC, the only machinery that uses CSS selectors to select nodes to do
work start through dojo.query calls. We could implement other APIs
that do not start with a query call, the live call being probably the
first, but I want to make sure it makes sense.

There is some API simplicity to saying that API calls with CSS3
selectors starts with a dojo.query call. I expect
dojo.query(node).closest(query)  vs. dojo.closest(node, query) are not
much different speed-wise particularly with expensive queries. I
appreciate not having the extra .query() in the API call, but if the
expense is a larger base and more API surface to explain, it may not
be worth it.
