Yeah, like other people covered, it's unfortunate but also very important. It's easy to tie "visible wifi networks" to "surprisingly precise location on globe" in many places, so the permission is named for the worst case scenario. Yes, the app might just be looking for a wifi, but it also could use that same information to locate you, so it's the location permission. Sensible.
If they wanted to support just this one feature without requiring a location permission, they could maybe have an API that is "are you currently connected to this opaque token" API where the app can ask "am I connected" and is just told "yes" or "no". That's probably safe enough. And then I could register the app with my wifi without the app even knowing what my Wifi is, it just gets a unique but random string.
The same is true of bluetooth. If I can list nearby bluetooth, I can see that speaker and this TV and guess location. But there could be an API that hides that, there just isn't currently




What does it mean access to the chapel and East Wing? Are those... not included? Is it a museum or something?
