After Jul 17th's Parquet Sync feedback I have updated the extensions proposal to remove the "reservation" mechanism. The updates are already reflected in the document <https://docs.google.com/document/d/1KkoR0DjzYnLQXO-d0oRBv2k157IZU0_injqd4eV4WiI/edit> and the PR <https://github.com/apache/parquet-format/pull/254>.
