Yup, I did that refactor with https://github.com/apache/hive/commit/2e916a3ec26a6d12653c89ad445fed91e1ba0cde so that we can acquire the commit lock from `HiveIcebergMetaHook` too. The reason why it was not ported to Iceberg was that Iceberg was depending on an old Hive version where some of the hooks (especially for alter_table) didn't exist yet.
