No, xf86 naming is still there, but you're kinda misunderstanding what a driver is. These xf86 things are tiny pieces for the xorg server. (Irrelevant with Wayland, obviously.) The real "meat" of the driver is in two places: Mesa and the kernel. The kernel module is the hard part. You can install the higher level parts without it, they just won't be useful. You can have the xf86 thing, and libdrm_nouveau, and Mesa dri_nouveau, they don't even require any porting, but they're absolutely useless without the kernel driver, they wouldn't have anything to talk to.
