> The place internally where the "legacy" `pyarrow.filesystem` filesystems are still used is in the {{pyarrow.parquet}} module.
> It is used in:
> - ParquetWriter
> - ParquetManifest/ParquetDataset
> - write_to_dataset
> For {{ParquetWriter}}, we need to update this to work with the new filesystems (since ParquetWriter is not dataset related, and thus won't be deprecated).
> For {{ParquetManifest}}/{{ParquetDataset}}, it might not need to be updated, since those might get deprecated itself (to be discussed -> ARROW-9720), and when using the {{use_legacy_dataset=False}} option, it already uses the new datasets.
> For {{write_to_dataset}}, this might depend on how the writing capabilities of the dataset project evolve.
