@prog-amateur Sorry for resurrecting this old thread but I had to answer this.
A-GPS is very risky in terms of privacy as the technologies we have today can easily point out your XYZ axes when current locations services are used.
supl.google.com is almost always included in the implementation of A-GPS. There used to be Nokia and Sony Ericsson and we all know what happened to them. Even other supl servers are already owned by Google.
So yeah, not having A-GPS is good enough for me. TTFF will take time to get a good GPS signal but the next fix will be much quicker.
