    • reword and update documentation on passive_updates=False; as virtually all DBs now support ON UPDATE CASCADE other than Oracle, there's no need to try to reimplement more functionality here and users should be encouraged to forego natural PKs unless their target platform supports them. references #2666

    most RDBMS now support ON UPDATE CASCADE, including sqlite. With Oracle being the only exception, this feature doesn't have much of a use case as natural PKs should only be pursued on backends with support for this use case.
