While I agree that it's not the best situation, (and I'm wholly against nvidia in this case.) And yeah this isn't about the mod-game api boundary, this is more about the mod-os boundary since that is harder to control against. WASM from my research so far doesn't allow any of that by default and it has to be passed through by the runtime. In this case it would be passed through to the retargeting compiler. This can give additional benefits like allowing mods on consoles in a more secure way and allowing for targeting the game to future cpu architectures without requiring all mods to recompile their code (not that I think the latter is a reason microsoft cares about.) But the idea of recompiling code when launching a game is already kind of standard on the gpu side of things.
