I am quite reluctant at the idea of making my Steam profile and library public. I understand it’s the easiest way to share your library with Lutris, but is there another way?
I don’t know if Steam offers this feature, but the idea would be that the user asks Steam for an API key and enters it into Lutris to give it access to its profile and library. This way users are in control of who can see their profile and library.
If Steam doesn’t offer this feature, I think Lutris would be in a good place to make such request.
