--- Comment #2 from Rick Byers <rbyers at chromium.org> ---
Note that our guidance to affected sites is to rely on CSS touch-action instead of depending on TouchEvent.preventDefault: https://developers.google.com/web/updates/2017/01/scrolling-intervention

Really passive touch listeners are only a reasonable choice when touch-action is fully supported - see https://bugs.webkit.org/show_bug.cgi?id=133112#c2.

Safari is likely to see more web compat problems than Chrome unless/until WebKit gets touch-action support.
