P2P was practically dead on iPhone even back in 2010. The whole "don't burn the user's battery" thing precludes mobile phones doing anything with P2P other than leeching off of it. The only exceptions are things like AirDrop; i.e. locally peer-to-peer things that are only active when in use and don't try to form an overlay or mesh network that would require the phone to become a router. And, AFAIK, you already need special permission for anything other than HTTPS to specific domains on the public Internet. That's why apps ping you about permissions to access "local devices".
