You are correct that this could get challenging without proper notions of units. Do we have a utility to transfer attributes from one Dataset to another? If not, perhaps that is the simplest, short term resolution to this issue that is even more general than addition of a `keep_attrs` flag. I don't think it would be to hard to write although it may be out of xarray scope.
