So, things that are either impossible (touch events or vibration) or ridiculous (why would I want a website to know my battery level or directly access system hardware?)
There are some use cases for those permissions but we (some) would like more control into that. I can't fight most of the websites as a user (they will tell me to use chrome) but it is for them hard to tell me if you want the service (along a billion other user) then move to android. Apple for a better or worse have much more sway than individual user.
