the referenced video was entertaining to watch (and i learned new things about typescript and proxies), but i still don't understand your UX-problem -- at least enough to know what/how a new standard-api would help.
there's a bunch of canvas-scrolling examples @ https://konvajs.org/docs/sandbox/Canvas_Scrolling.html. examples #1 and #4 implement native canvas-scrolling, with the latter having less jankiness on my mobile-chrome. maybe you're asking for consistent #4 css-behavior across all mobile-browsers (i have no idea if it works as well in ios-safari)? that would be w3c csswg's domain. also somewhat-related -- chrome is debating an intent-to-implement feature for scrollTo-behavior for text-fragments. for example: `https://www.example.com#targetText=You%20may%20use%20this%20domain` will scroll to element in www.example.com containing text "You may use this domain".
