Earlier quoted context omitted.
Everyone operates an AGPS service these days. Without it, you'd have to wait at least 12.5 minutes from a fully cold start (and likely, if you missed a data packet, double or triple that) until the GPS receiver has all the almanac data [1]. [1] https://en.wikipedia.org/wiki/GPS_signals#Almanac
In my old Nokia N95, the AGPS data was downloaded when starting the GPS app. No need to require a constant background download.
I may actually use gps once or twice a week only, disable geolocalisation when it is possible on all apps I am using.
There is no justifiable reason to say gps is not possible without this. Besides you should be able to decide you don't mind waiting 15 minutes to get full gps service.
