Right, and I can see times when I'd really prefer this behavior. Especially in incognito mode. But let's say at worst case we could categorize those or allow a settings page where I could switch these to opt-in-by-hostname/opt-out-by-hostname.
I'm using it (along with uBlock Origin, EFF Privacy Badger and custom Tampermonkey scripts), and while I like the sense of control, I also think it's obvious that fine grained control for such details or further details like battery status is not what most users want or even could handle.
Sometimes it becomes really annoying and I give up on figuring out what minimal set of features a site needs, and I open it in an incognito tab where only uBlock Origin is active.
I'm also thinking about another kind of plugin - one that simply monitors access to browser API calls required to get information like resolution, mouse pointer position, battery level, etc. and that would display you only the "spying level" of a site as an icon. Like the padlock icon, changing colors from green to yellow to red or something, and that would expand when clicked to show something like this:
Spying level: MODERATE.
