i can't remember the conclusion about an install warning, but I guess one wasn't
required?

Not for dev channel. Whitelisted apps will have their own privacy review and may
be required to show some sort of permissions dialog (considering we are
unauthenticated now, the privacy requires are somewhat relaxed).

The final install warning for this has not been decided yet, but before we open
the API up, it definitely will be.

I don't think that "it's dev channel" is a good reason to avoid an install
warning. And I'm not sure that the privacy implications are much different, an
extension can still figure out who you are through other APIs. Could you at
least make it "communicate with nearby devices" or something? anything?

Done.
