I imagine Larian care. Especially since they’re pushing Steamdeck support.
The reason this is a “supported platform” issue is that the developers of Hogwarts legacy know their supported platforms support XeSS, so any work that is not “just turn it on” is additional work for no gain.
Only in the same way that stealing code from a PoC would make me racist, stealing code from a Jew would make me anti-semitic or stealing code from a woman would make me sexist.
Since, without proof of any of that you’re just making shit up I’m going to go with the reason that your post is being downvoted is that ITS JUST FUCKING STUPID.
