The interesting ones are only supported by chromium browsers.
Alternatively: the invasive ones are only supported by chromium browsers.
Also true.
A more optimistic viewpoint: because of the popularity of Chromium based browsers (for better or worse), caniuse.com suggests some of these features have ~70% global browser support - not terrible in my opinion.
Also because of the nature of these features (depending on use case), you can use them in a progressively enhanced manner.
