My concern with allowing all apps access to ~/.cache/QtLocation is that it would be possible for an untrusted app to collect cached map data without the user's knowledge and send it off somewhere, which is why we don't share other caches (such as oxide's web cache). It would probably be ok to have an out of process trusted helper give access to/display these files in some way such that when an app contacted the trusted helper, it would display a trust prompt allowing access to shared location data.

I suggest to modify the plugin so that: 1) Tiles are stored in a common place (and apparmor rules are relaxed to allow read access to that): ~/.cache/libqtgeoservices_osm/, for example 2) Tile downloads are managed by a separate service, started on demand.
