In the past, depending on pyarrow version, you may or may not have had access to arrow strings, dask.dataframe query planning, and p2p shuffle (and the three features required three different minimum versions).

All of these are obsolete now that dask.dataframe's only engine is query planning, and that pyarrow's minimum version is >=16.
