Well, just for getting cell info - yes, should be enough to query 
ofono(?) through dbus.

For my case, Inned more info, like device model, OS version, etc. So 
custom-built libQt5SystemInfo.so.5 is a drop-in replacement until Qt 
SystemInfo gets whitelisted: I'll only have to remove it from the RPM 
without needing to change anything in my app.
