This is the best approach that I've seen.

Assuming a sliding scale, site picks the value that they would find acceptable, or might like.  If the user is concerned, they provide only that minimum.  It's a negotiation, so either party might have to compromise.

Site wants 10m, user says 50m; site is disappointed
Site says 1000m, user is generous and says 200m; site gets more than they need

The problem with enableHighAccuracy is that it essentially has no semantics.
