Well, not all unused Wayspots become Power Spots.
@EmonPeregrine PoGo has density rules for stops, gyms, as well as Power Spots, all of which have been observed by the community. Only 2 active Power Spots are allowed within a L14 S2 cell at a time, and a Power Spot cannot be within 22m of an active stop/gym. So while getting more Wayspots added to the Wayfarer map may help, there’s no guarantee that any Wayspot will be added to PoGo.
For more info on the inclusion/density rules of PoGo, please see the following:
