Greenmangaming was doing this a decade ago. Steam wouldn’t be the first,but it might be the one to get it to stick.

(Ironically, it was predominantly steam games at first that couldn’t be traded on GMG)

What you say is not untrue, but I think the poster above would be fine with no zoom and only moderate camera(s) if there were no bump. I’m certainly in that boat. Unfortunately, as the first surface duo showed, there’s basically no market for no-bump low quality cameras on decent phones.
