Part of this is due to limitations in how iOS communicates this to users. "Always" can refer to either (1) always-on GPS, or (2) Bluetooth, which will ping app-owned beacons. The Bluetooth option is significantly narrower in scope, but uses the same dialog as the GPS. I worked for a company that relied on Bluebooth beacons to provide a critical app experience (notifications before app itself is opened), so the app blocked the login screen until the Bluetooth-driven "Always" location authorization was granted. It was a headache explaining to users.
