I frequently need to pull out the dimension names, and I've never needed to pull out their sizes. I realize that the internals need to do that though. And maybe my use case is specific.

Zooming out a bit: the access pattern for most of these (variables, coords) is indeed an OrderedDict of name to object. But the stickler for dim is why the size should be the value here? It seems very different from having dim objects as values.

I could certainly understand a convenience dims_shape (for {dim: ds[dim].shape for dim in ds.dims}.

But I"m coming from a place of less context without that much confidence...
