LGTM with a question

Why doesn't this need the externally connectable any more? I'm happy about that
(hence the lgtm), but curious as to why.

Because we don't get woken up by google.com. None of that code exists in this
extension, google.com doesn't know about this extension, and I don't think it
makes sense for this extension.
