BridgeDB should consider a user's location
bridges.torproject.org knows the user's physical location and should consider it when returning bridges. For example, if somebody in country X asks for an obfsN bridge but BridgeDB knows that only obfsN+1 works in X (e.g., by consulting the result of #28531 (moved)), it should return obfsN+1.
Ideally, we would do this for all of BridgeDB's distribution mechanisms. We could also do it for email – if the user emailed bridges+CC@bridges.torproject.org. As I understand it, we cannot do it for moat because BridgeDB doesn't get to see the user's IP address in this case.
