Developers mess this up as well.. you should only need to agree to location to pair your device the first time and the permission can be revoked after.. because the app should save the hardware id of the paired device. Many developers choose to have their app not function if this permission is removed, even though it is not needed. I've written a number of companies and gotten them to fix this, but Google is doing the biggest disservice by making it so confusing. I get the security aspect, and it's valid, but somehow they've made it impossibly confusing for both developers and end users.
