Why do "geolocation in the background" vs "geolocation in the foreground" need to be distinguished?

I believe that a site with geolocation permission that is open in a tab already has the ability to continuously poll for geolocation.

Adding a System Wake Lock just allows the site to ensure that it isn't unloaded by the browser, but there are other ways to accomplish this already, including keeping a WebRTC data channel open, playing a silent audio file, etc.

In other words, I don't think this API actually enables anything that wasn't already possible, just makes it a bit easier to accomplish and provides a better guarantee that the CPU will stay active.

Now, if we're allowing a site to wake itself up and get geolocation *after the tab has already been closed by the user* (say by using a service worker), then I believe a separate permission would be warranted. But this API isn't doing that.
