Yes, that is absolutely a use case. Similar to Venmo, there is also a Request for Payment (RFP) mechanism. I'm on the Request for Payment (RFP) Work Group that is composed of a number of financial institutions, service providers, and billers.
Netflix is part of the RFP Work Group. So presumably they are interested in offering consumers the ability to pay for Netflix using FedNow instead of a credit card. Instead of Netflix paying ~$0.50 in credit card processing fees per U.S. subscription they'll probably be able to find a bank willing to charge them < $0.25. It also gives consumers more control as they have to authorize each charge.
