They're likely doing it so they can support the current x64 apps easily on the ARM chips they're supposedly building in a Rosetta like fashion. You could use all sorts of ways, but if the underlying CPU changes it becomes emulation vs virtualisation. The performance hit is likely enough a cost for a large amount of people to move on despite the old ways never going away
