   @dmgcodevil: The purpose of the Hive Lock is to make sure that there are no concurrent changes to the table. Specifically that there is no concurrent Iceberg commit.
   
   In theory the replace is a good idea, but in an ideal world that is a new feature in HMS which could be only supported in the upcoming releases (4.0.0). Most of the Iceberg community uses older 3.x Hive (HMS) version, or even older 2.x some cases. Adding a new feature there is usually not allowed.
   
   Just from the Iceberg perspective this change would be very much needed and welcome as it would mean faster/more reliable commit flow for HiveCatalogs
