DLSS mods and generic training mean that it could be universal someday

Just came across this https://www.nexusmods.com/fallout4/mods/68586 and confirmed that since DLSS 2.0, Nvidia no longer uses game-specific training for DLSS (instead they rely on a "generic" training model).

So hypothetically, we could see DLSS for all games, right? It's a matter of time before similar mods come out for other games. Could Nvidia just let us do this via driver update someday?
