Is there any reason to make use of the mux?
Performance (lower latency => no need for framebuffer writes over PCIe), improved battery life (no need to use 2 GPUs simultaneously).
Technically you can't just ignore that the mux is there on the MBP because the kernel has no control over the GPU used on boot. (It's determined by EFI).
Is GPU power switching also handled by the mux? Is it independent of the display mux?
Yes and yes.
Best regards,
Lukas
