            Due to the regression MDEV-16664 (potential corruption due to wrongly granting exclusive locks on the same record to more than one active transaction at a time), I did the following:

            1. Reverted the default back to the safe value
            2. Added a deprecation and corruption warning
            3. Removed the option innodb_lock_schedule_algorithm and related code (MariaDB Server 10.6) that had been added in MDEV-11039.
