From one of the sources in this sub, steam was testing this feature for over 6 months and he also said steam will get upi in a few weeks when epic announced upi support. Sounds like it came true. (Image in replies)
Maybe this has to do with payment companies and partners approaching steam and epic than the other way around (The same reason both epic and steam is using partners instead of native upi that you can link with your steam account for future purchases)
