It’s a different layer for those though. In each of those other cases, the code paths that diverge per app are not within the app libraries but within the system SDK or the graphics driver. Those are layers the application has to trust , and also has expectations may change implementations. They’re only accessible as an API. In this case they were stepping into code they don’t control which is a huge violation of trust
