I didn't really see a point in AMD pushing Zen 3 any further. Alder Lake is not out for another while. When it does, I can imagine it will only top the score charts in single-threaded benchmarks. And it'll only do that for one quarter or so until Zen 4 is out. I see no point in AMD pushing for a refresh or a clock speed boost at this time. Zen 3's biggest hurdles are the production (especially of their flagship Ryzen products), X570 chipset heat, and no budget options. With the B2 stepping X570S chipset, that's the first two hurdles dealth with. And if Alder Lake does indeed beat AMD, they can drop the prices of their current lineup or release non-X variants to retake the 'consumer' crown (budget CPUs) and retain the multi-threaded crown that they've held on to for four years now.
