-// of Bluetooth devices the origin is allowed to access. For each device in the
-// allowed devices list for an origin, the UA must maintain an allowed services
-// list consisting of UUIDs for GATT Primary Services the origin is allowed to
-// access on the device. The UA may remove devices from the allowed devices list
-// at any time based on signals from the user. For example, if the user chooses
-// not to remember access, the UA might remove a device when the tab that was
-// granted access to it is closed. Or the UA might provide a revocation UI that
-// allows the user to explicitly remove a device even while a tab is actively
-// using that device. If a device is removed from this list while a Promise is
-// pending to do something with the device, it must be treated the same as if
-// the device moved out of Bluetooth range.
