I still consider adding a nVidia card and not also using it for your monitor(s)
a corner case. Having both enabled in a laptop by default is different to that!

I consider this a corner case and I don't think this will still happen with
obsolete X11 technology.

I believe this already happens when nouveau driver is loaded. An unused nVidia
card is not running in full speed then.

"prime-select offload" is already there for Laptop Optimus systems, so nVidia
is only waked up if needed for 3D graphics rendering. But Turing platform or
later is needed for this.
