Anyone know what #google ULR is?

"Suppose a user has disabled permissions to, say, Google Maps for Mobile (GMM). With client-side location, GMM will not get location, as the user intended However, they can still get a place card (e.g. Riddler) via ULR-->████-->GMM server--> GMM client. (URL has GmsCore's location permissions, not GMM's). This seems like a bypass to Android's permissions model."
