-// When a website requests access to devices using requestDevice, it gets the
-// ability to access all GATT services mentioned in the call. The UA must inform
-// the user what capabilities these services give the website before asking
-// which devices to entrust to it. If any services in the list aren't known to
-// the UA, the UA must assume they give the site complete control over the
-// device and inform the user of this risk. The UA must also allow the user to
-// inspect what sites have access to what devices and revoke these pairings.
-//
-// The UA must not allow the user to pair entire classes of devices with a
-// website. It is possible to construct a class of devices for which each
-// individual device sends the same Bluetooth-level identifying information. UAs
-// are not required to attempt to detect this sort of forgery and may let a user
-// pair this pseudo-device with a website.
-//
-// To help ensure that only the entity the user approved for access actually has
-// access, this specification requires that only authenticated environments can
-// access Bluetooth devices (requestDevice).
-// """
-//
-// From: Per-origin Bluetooth device properties:
-// """
-// For each origin, the UA must maintain an allowed devices map, whose keys are
-// the Bluetooth devices the origin is allowed to access, and whose values are
-// pairs of a DOMString device id and 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 map at any time based on
-// signals from the user. This needs a definition involving removing
-// BluetoothDevice instances from device instance maps and clearing out their
-// [[representedDevice]] fields. 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.
-// """

-// From: Device Discovery: requestDevice
-// http://webbluetoothchrome.github.io/web-bluetooth/#device-discovery
-// """
-// Even if scanResult is empty, display a prompt to the user requesting that the
-// user select a device from it. The UA should show the user the human-readable
-// name of each device. If this name is not available because the UA's Bluetooth
-// system doesn't support privacy-enabled scans, the UA should allow the user to
-// indicate interest and then perform a privacy-disabled scan to retrieve the
-// name.
-//
-// The UA may allow the user to select a nearby device that does not match
-// filters.
-//
-// Wait for the user to have selected a device or cancelled the prompt.
-//
-// If the user cancels the prompt, reject promise with a NotFoundError and abort
-// these steps.
-//
-// Add device to the origin's allowed devices map. with the union of the service
-// UUIDs from filters and options.optionalServices as allowed services.
-//
-// Get the BluetoothDevice representing device and resolve promise with the
-// result.
