This is definitely a case where the documentation has gotten out of sync with the implementation (I used to abuse a dataset argument in DataArray.__init__ for a fastpath constructor, but now I have another method for that). The data argument is not really optional right now (unless you want a scalar DataArray containing the value None).

Your proposed functionality does sound useful. Do you want to take a crack at the implementation? The init logic for DataArray is pretty self contained, and it's all at the top of xray/core/dataarray.py. It will require a small amount of reorganization because _infer_coords_and_dims currently assumes it already knows the shape of the data.
