This would be a nice feature to have, but indeed would likely require pervasive changes.

The other option would be to explicitly compute the shape when converting from dask dataframes, by calling `dask_dataframe.shape[0].compute()`. This would probably be more straightforward to implement but could potentially be pretty expensive in speed/memory.
