I'm not disapproving of the growing unbounded set of restrictions; I'm
 saying that the fact that by opting in to sandbox, you're opting in 
to a growing unbounded set of restrictions makes it less likely people
 will be opting in. I prefer the model where the default is right.

OK; if this is the direction where the overall platform is going 
toward, it probably does not make much sense to make `getUserMedia` an
 exception. Since I suspect there are many more cross-origin iframes 
than there are sandboxed iframes, I don't think that's great, but I 
agree there is value in consistency, especially noting your other
