As much as I like Valve’s work, I don’t think thats a good fit for them. Their staff seem to enjoy working on difficult technical tasks, and lose interest very fast when it comes to mundane maintenance, thus their numerous underutilized and unmaintained features throughout Steam and their games. A payment processor seems like exactly the sort of thing that would get forgotten about a month or two after it gets finished.
From what I understand, they’ve moved on from that structure. I believe that was one of the things talked about after the release of HL:A, with one of the employees saying that it was part of the reason the game actually got finished. That said, its been a while and even assuming I’m not misremembering information rarely leaves Valve, so I could be wrong.Edit: I’m wrong. See sp3ctr4l’s comment below.
