%SYS.Task.UpdateSQLStats , %SYS.Task.FrozenPlanScan,%SYS.Task.CleanSQLIndex Depreciated 2022.1?

Hi:

Are these all depreciated in 2022.1? Our tasks don't run as can't find it and using a search of the docs they are last recorded against 2021.1?

Search InterSystems Documentation
There isn't any line in release notes to note that these no longer exist.
