The recommended actions are built around the assumption optimal gaming performance is the only market segment to please. Of course, efficiency cores were never about pleasing that segment anyways - gamers want fewer huge cores, not lots of big cores or tons of efficient cores. That Windows gaming is slightly imperfect due to scheduling difficulties will not stop AMD, Intel, ARM, etc from continuing to use different sized cores on non-uniform interconnects if it means larger changes in perf/watt and perf/cost for that price.
In practice this is more of a problem for gaming news site headlines than users anyways. For all but the biggest enthusiast the uplift from going to a new system is usually so much they'd not notice it could be a couple percentage points better or that one game is still a bit hitchy. It's us ultra-nerds that care about the 1% lows between different top end CPUs, and we tend to be quickly convinced the problem is Microsoft's to solve for us when the scheduling problem hits ARM, AMD, and Intel based Windows devices equally.
