Maybe a dumb question, I skimmed the post but it's a lot to take in. Would this potentially enable third party integrations, like Venmo or sending money through iMessage? That's something I've always been a bit jealous of with Americans. E-transfer has been fine but it's clunky.
Isn't "etransfer clunky compared to venmo" just a function of how your particular bank has designed their app UI/UX?
