The question I was looking to answer was whether I could open tab A, 
get a deviceId, and then open tab B to the same origin and get the 
same deviceId.  I'm not clear on whether that would work based on 
https://github.com/w3c/mediacapture-main/issues/359#issuecomment-218928754.
  Also, if I navigate away, then hit the back button, what then?  Lots
 of other page state is maintained, would this be cleared?  Would it 
then be inconsistent with the rest of the page state?

FWIW, it's fine if a browser decides to expire device identifiers on 
whatever timescale they deem appropriate.  But while I think that the 
availability of that choice is important, I don't think that clearing 
in this specific fashion helps. Indeed, I would prefer if browsers did
 not clear like this, but I am happy to keep this a point of browser 
choice: we each make different trade-offs in this space.
