These apps have been actively working around or finding good ways to avoid waking the dGPU. In some cases the dGPU monitoring widget is disabled until the user requests it.

It is a continuous issue. If I had a dollar for every message in my discord channel asking why the dGPU is not sleeping I'd have a few thousand in savings now.
If the only way to prevent this is to return error if in d3cold then I'm 110% in agreeance. If apps can't handle that possiblity then it will force proper handling and prevent all future issues like this.
