Introduced in GNOME 3.36 are granular privacy settings to control which apps have access to Location Services, Camera, and Microphone. However, at least in package gnome-control-center 3.36.0-1, these settings appear to do nothing. If I toggle off location services, GNOME Maps and GNOME Weather ignore this and continue to work as normal. Likewise, no apps like Cheese, OBS, Skype, Telegram, etc area asking for Webcam or Mic permission, though all of them are using these services just fine.

I'm not sure if these are meant to be Flatpak specific toggles, though the point still stands. I tried both Flatpak (through flathub) and native ArchLinux variants of all of these packages, and none of them asked for permissions, nor were affected when disabling any of these permissions. So, something appears to not be wired up correctly.
