Many navigation systems exist beside GPS...... which is itself one of four Global Navigation Satellite Systems (GNSS).

These systems are all still capable of returning a position of (0,0) though. My point was that if it becomes commonplace for software to filter points around “null island” then that would gradually permeate various libraries and create a little blind spot

Of course....

....and my point was that positioning solutions should not solely assume GPS, otherwise some nasty surprises can lie in wait.
