GSettings is the wrong location for that. Current location and time zone
settings should be queried using dbus from org.freedesktop.timedate1, and the
GPS service (not sure where that is yet).

There shouldn't be that many system-wide gsettings that are interesting for
applications. Most of them should be available using an API or via dbus.

Yes, that would be correct.

Yes, those are considered part of the core apps. If necessary, they can run
unconfined, but we'll attempt to confine most of them to protect the user's data
and privacy in case of security flaws.

Again, that should be done using the proper dbus org.freedesktop.timedate1
interface.
