Ticket 50224 - warnings on deprecated API usage
    
    Bug Description: There have been many cases of incorrect and
    invalid api usage. As we go on, we can't allow more usage of
    these apis to be added as it only puts more work on us in
    the future to remove.
    
    Fix Description: Add deprecation warnings to these apis, telling
    people they will be removed, and where their faulty code is.
