The second one also provides more scope to remove subsets of data (all corresponding dims, coords, vars) if the dimension becomes superfluous for any reason, whether or not the dimension is empty.

Note that in general we try to encourage using methods to create new Datasets rather than modifying existing ones inplace. So it might also make sense to add a drop_dims() method that return a Dataset with the given dimensions removed.
