You don't have to add every single person that is a contact, you'd just be able to see they are connectable. Maybe I would like to connect on FitBit with my personal trainer but not on Instagram or Pokemon Go. Anyone I consider a friend that I didn't meet online I will always have their phone number, even if that isn't my primary form of communication with them. A phone call will always go through without regards to any data limits and is less spotty in areas with bad service. I'd love it to be a standard so that social networks could also be connected together in a similar asymmetrical way but that would require even more cooperation from people proven to be bad actors.
