    It depends on the significance of the change. I suspect it's one of
    things which speeds up many workloads by 1.5% and slows down a few
    weird/important ones by 11%. Which makes it a thing to be put under
    the microscope and poked at. Some people might end up reverting it,
    making it tunable/configurable etc etc.

    If any of that is true then yes, I guess it should be a standalone thing.
