    The policy is very simple and common-sense: if a given piece of PMU
    functionality is useful enough to be exposed via a raw interface, then
    it must be useful enough to be generalized as well.

    FYI, this is how the Linux kernel has operated from day 1 on: we support
    hardware features to abstract useful highlevel functionality out of it.
    I would not expect this to change anytime soon.
