What are the arguments against having dims be a tuple for both DataArray & Datasets?

I guess that's a third option! In that case, we'd have to add shape to Dataset, too, to ensure there is some way to get size information.

The main downside is that we'd still be stuck without any idea way to get dimension sizes by name -- ds.shape[ds.get_axis_num('time')] is pretty bad. Also, I'm not sure how many use cases there are for actually pulling out the first dimension of a dataset (or it's shape) by position, given that dimension order is currently sorted independently of dimension order on any of its data arrays.
