wot gymnastics? It's SteamOS: Just use the Steam frontend to play any of your games, or go desktop and use other launchers to run the game that's outside of steam (Lutris, Heroic, etc etc)

Now if the 'gymnastics' you're talking about is SOME *cough* game *cough* that uses the Bepinex framework (Unity Mono, Il2cpp, et cetera)... just lay out the winecfg and put in winhttp in the libraries. Done.
