Fingerprinting. Every w3c specification that adds features to the platform adds more unique data that can be used to identify you. They try to add security to the sandbox to make sure the user has to give permission to the website to use these APIs but it's always a cat-and-mouse game to make sure that there are no ways to break out of the sandbox and to educate users about what all these modals and features mean. Websites are getting obnoxious these days. Most tracking software on them will trigger all kinds of authorization modals for various APIs. And you can bet there will be a bunch it will try to use without authorization if there's a work-around. It's all fingerprinting to sell data.
