Exactly, wine is all that's needed here for windows stuff. And we have snap, flatpak, docker, and a few other things for Linux stuff.
We'll probably get a bit of irony in a few years when somebody at MS realizes that they can just use wine on top of their Linux emulation layer to run any old MS legacy software from the past three decades+ and then cleans up the rest of windows to not have any support for legacy APIs. Because having that is redundant. Emulators are great. There's no need to run ancient software natively.
Someone should develop an analog for Linux itself. I.e. support for older / historic ABIs that would be translated into whatever modern Linux has.
Some isolated example of that is SDL 1.x translated to SDL 2.
Wine itself already exists, you don't need to develop any new distro for running Windows programs on Linux. Just improve Wine if anything is missing.
