This will be a positive if browsers (extensions?) allow the ability to spoof visibility by site. Most websites have no business knowing if they're in the foreground or background.
Nice - you’ve just increased significantly power consumption of your browser!
Browsers will “slow down” various aspects of pages when they’re not visible, like animations or timers, to save on battery usage on laptops or phones.
Even if your remove explicit APIs for backgrounding, pages can still use heuristics to detect anyway.
That's actually quite easy. onBlur, etc
