This is talking about wideband location scanning, not location services for an app. Apple's location services already do allow you to turn them off on a per-app basis.
Who cares if your Apple device constrains location information when, stochastically speaking, other devices within your proximity won't.
This has been meta for a long time: WiFi, Bluetooth, cell towers, TPMS, just to name a few common mappings. UWB is yet another PHY contributing to the datapool.
