I was thinking that way in the past. But then, the only stable ABI is the win32 one.

The linux kernel one is very stable, but the libs ones isn't.

As soon as the dev ensure and cooperates with wine/proton to make it work nicely, i'm game.

Needing those old libs in linux is rather cumbersome, if at all possible. So having wine doing the translation layer is a really good thing. As it frees the devs to be able to focus on 1 plateform.

I also noted that the switch enabled a lot of linux native ports. That's also a nice side effect.
