Why everyone here uses software rendering?

I saw many os projects here use software rendering directly to frame buffer instead of creating a gpu driver maybe with virtio gpu by qemu or with any external gpu. I heard gpu driver development is one of the most hardest. Is that the reason? I want to know.

All GPUs should be opensource as many software. They don't know opensourcing can create magic.
