That didn't stop Nintendo from being successful in selling the same game 2 or 3 times on different consoles in their digital emulator.
My guess would be something like this:
>people buy quest 3
>people now either stay with it because casual, or they get more interested in it and connect it to a PC for steam
>there people branch of again into "oh that is enough" and "Damn there has to be a better way"
And exactly those people are the market I think Valve would be interested in. Selling the quest 3 to essentially get the index 2 at a discount (so to speak)
