Can the video part of an auto-playing video also be distracting? I guess 2.2.2 Pause, Stop, Hide covers this part to an extent, though I think that doesn't actually explicitly talk about video per se. > Agreed, although thinking about this, maybe the answer is not "no > auto-play" but rather, "no auto-volume" (without user input).

Would it make sense to add some form of "the mechanism to (turn off audio / pause,stop,hide moving/blinking/scrolling content including video) must be easily discoverable/reachable" to the existing 1.4.2 (for audio) and 2.2.2 (for video) (both at Level A) and then make one or more new SC(s) that cover having a mechanism to prevent autoplaying audio or animated/moving/video content altogether, at level AA ?
