Scroll anchoring should benefit both desktop and mobile content. I have a feeling the biggest impact will be on mobile though. Scroll anchoring should help there when the viewport resizes from a rotation, not just as content loads.
There's a good video in the Chrome announcement here [1]. I've also written two sample pages that you can compare between Blink and Gecko [2] [3]. Scroll down and interact with the button/slider.
