Your copy&paste does not support your argument. Just looking at the top items on your list, it's basically a bunch of Safari-only features which no other browser vendor ships:
- CSS Canvas Drawings is not a web standard. It's a WebKit-specific feature, only Safari implements it. Chromium removed it in order to replace it with an actual web standard (CSS Painting API).
- Likewise, the CSS filter() function is Safari-only.
- U2F API has been deprecated for years, was replaced by WebAuthn, and only Safari still implements it.
- Same with SPDY, which was replaced by an actual web standard (HTTP2). Only Safari still ships it, but has marked it deprecated.
- SVG Fonts were removed from the SVG spec.
- HLS, JPEG-XL, HEIF/HEIC are essentially Safari-only as well.
CSS hanging-punctuation and audio/video tracks are new features that haven't been widely implemented yet.
