[Bug 25245] Specify "access" in the context of getMediaDevices

https://www.w3.org/Bugs/Public/show_bug.cgi?id=25245

--- Comment #5 from Martin Thomson <martin.thomson@gmail.com> ---
The best usability argument I have to hand is this:

A user frequents a site that uses gUM, but does not provide persistent
permissions (maybe because they use the peerIdentity constraint exclusively). 
The site is able to use the device identifier, which is stable, to ensure that
the same device is used every time.

The site is able to detect when that device is not available and use the device
identifiers to provide predictable fallback behaviour.
