> Currently, the {{pq.write_to_dataset}} function also had a {{use_legacy_dataset}} keyword, but we should:
> 1) in case of {{use_legacy_dataset=True}}, ensure we raise deprecation warnings for all keywords that won't be supported in the new implementation (eg {{partition_filename_cb}})
> 2) raise a deprecation warning for {{use_legacy_dataset=True}}, and/or already switch the default?
