Not really necessary, all major makes and models are already there. DDR 4 haven't changed much and XMP profiles are all same. Nobody really makes Ryzen only RAM. For now all RAM up to 3200MHz will work in all Ryzen MBs and Ryzen itself can go as high as 4000MHz.
If in doubt about your chosen RAM, just look up RAM with similar characteristics in QVL. That's all that's needed. Ram with Samsung "b" die works guaranteed best.
