With smart lock services requiring hosting and registration and ip-block and cloud IOT expenses, I'm surprised that this isn't happening already to be honest. Also that per token issue fees aren't being assessed by open id or sso providers. They could especially game the system by decreasing the ttl of tokens to smaller durations, and by instituting load-based pricing .
