> PIX will not be a service to end-users, it'll create a standard where any service can offer instant payments and transfers.
Great. If that "standard" is something people want, it'll be able to succeed on its own merits, without having to block the competition.
What happens when someone wants to create something new and interesting that isn't supported by the "standard"? What happens when that standard lacks features people actually want? The danger of forcing everything to use a single underlying framework is that you prevent anyone from being able to do better and improve.
