Great re the dimensions!

I reviewed the tests more fully, they look great.

It looks like we need a requires_numexpr decorator on the tests — would you be OK to add that?

Could we add a simple method to DataArray which converts to a Dataset, calls the functions, and converts back too? (there are lots of examples already of this, let me know any issues)

And we should add the methods to api.rst, and a whatsnew entry if possible.

Does anyone have any other thoughts? I think the API is very reasonable. I could imagine a more sophisticated API that could take a single query, rather than a dict of them by dimension — currently it's da.query(x="x>3", y="y>4"), but that would require more work and decisions, even if it were preferable.
