RE: Comments/Questions on Media Capture Streams – Privacy and Security Considerations

Even when there is a visual indication people can miss it or not understand
what it is . Given the sensitivity of having a "hot" mike/camera, persistent
permissions should also have an expiry so even if people are unaware of them
they will not be there for perpetuity.

In general all permissions should have an expiry in my view, with the
duration reported when the permission is requested. (i.e. this should be
part of the permissions API, not just MediaCapture). Those that are less
sensitive may have a longer duration but MediaCapture should be relatively
short (hours?).

In this case, my earlier criticism was based on insufficient information. I 
think this does what it is supposed to do. I still think that persistent 
(forever) permissions are a mistake. But this is mitigated by the fact that 
the browser indicates when mic and camera are "on".
