The 580 driver does support wayland, it's not that old. Or are you worried about future breaking changes since you won't get updates?
I just switched my sisters old laptop with a 970m over to the nvidia-580xx driver, available on the AUR. Further manual maintenance should be unnecessary until the kernel becomes too new for that.
I even had to enable wayland for GDM because it was trying to use X11 and failing.
She plays minecraft and a couple other games so the nouveau was not an option.
Linux does. Not all, but a lot, and more every day.
It's been years now, and it still hits me sometimes how insanely nice it is that my computers now work the way I want them to.
