It would be nice to have a graphical way to enable/disable location services in KDE, perhaps under the privacy category in system settings. GNOME also has such an option.
I can see this being a privacy concern and should be relatively easy to implement
To my knowledge, the only thing we have right now that uses any kind of location services is Night Color, which can be disabled right there on its config page in System Settings. But if we add more location services in the future, this would be a good idea, yeah. Until then, implementing such a thing would be premature.
