Summary Making document-level touchstart/touchmove listeners passive by default

Chrome is planning on shipping a breaking change (https://github.com/WICG/interventions/issues/35) to make document-level (window,document,body) touchstart and touchmove listeners passive by default. We've seen huge scroll performance improvements (~40% overall reduction in 99th percentile scroll start time) and relatively little breakage from this. If we can succeed in moving most remaining websites to adopt touch-action (a very simple fix) and therefore show that such a change is entirely web compatible, is this change something the WebKit project would consider? Or is there any reason (other than web compat concerns) why it would be a bad idea for WebKit?

Forward duping to https://bugs.webkit.org/show_bug.cgi?id=175346 (because it has more content) *** This bug has been marked as a duplicate of bug 175346 ***
