The point is that just because you don't want most sites to use these features doesn't mean that no use exists. I just want to make sure I don't get nag notifications begging me to turn it on every time I visit a news site.
Notifications? I need those from my calendar app and chat app.
Badges? Messaging systems I use rarely but which are important.
Visibility? I want resource intensive apps to "sleep" when not in use.
USB? I want an Arduino web ide to be able to communicate with hardware.
Screen lock? I don't want the machine to go into sleep mode when I'm presenting a slide deck.
Key lock? I don't want the browser intercepting keystrokes in my word processor or SSH session.
