Too many of those features are literally not on any standards track (Background Sync, User Idle Detection etc.) Too many of those features are literally Chrome-only non-standards that both Firefox and Safari oppose and won't implement (WebUSB, WebSerial etc.) And yet, as is the case with such lists, they are presented as actual standards and used in the crusade against anything non-Chrome (which implements all those and enables most of them by default)
