Chrome-only non-standards that both Firefox and Safari are against.
> Declarative Shadow DOM
Actually proposed by Safari, and stalled for multiple reasons. Moreover, at the start of the whole web component brouhaha Safari wanted to have declarative ways of specifying Web Components, but Chrome said "no, we want to move fast and break things"

Can't be bothered to check others, but off the top of my head, but most of other standards that you just dumped without understanding fall under the following categories:
- Chrome-only non-standards with multiple issues that have multiple objections from both Safari and Firefox
- Originally proposed by Safari
- Have specific technical objections from Safari, and specific reasons for not implementing
- (very small minority of specs) No idea why they haven't implemented these yet
