I think will be a nice feature if kdeconnect could read GPS position from the phone and send it to the computers. 
One of the potentials I thought is when the phone and the computer are connected through a VPN network and not on the same access point. In that case, the phone and the computer can be very far away. In that case if the phone is lost making it emit a strong noise may not be enough, that's when will be nice to get GPS position of the phone.

Another possibility (and the one I am most interested) is to use kdeconnect as an "API" to easily get a GPS position using the phone instead of buying a dedicated GPS hardware for the computer. Although this last one may seem more like a hack.
