the topic is on competion with zen 3, so the main market its adressing is the laptop/desktop business. they would have to rewrite an entire OS system in order for it to take off for consumers, consumers only care if all the stuff they need works, includng any industry level stuff. if they are only designing a laptop to do basic shit, there would be zero reason to develop a different cpu when they already have the low power consumption market in the bag. the only reason why you would target zen 3 performance is you plan on supporting industry level applications consumers may use (e.g adobe suite) which of course requires cooperation with any businesses attached to it, and tight integration with the OS.
