  1. Promote all inputs to Datasets (or @friedrichknuth's "dict_like_objects")
  2. Do the combining

I agree.

  1. If the result has only a single variable then demote from Dataset to DataArray?

I think the simplest solution is to always return Dataset? Then behaviour is always predictable. Otherwise you could combine a bunch of Datasets with a single variable and end up with a DataArray. Alternatively, return a DataArray only when all inputs are DataArrays with the same name.
