A holdover from citra, the Horizon kernel on the switch has no prominent kernel object that functions as a timer. At least not to the degree of sophistication that this class provided. As such, this can be removed entirely. This class also wasn't used at all in any meaningful way within the core, so this was just code sitting around doing nothing. This also allows removing a few things from the main KernelCore class that allows it to use slightly less resources overall (though very minor and not anything really noticeable).
