I hope NVK can one time surpass the current nvidia driver, at least for the needs of a basic (possibly gaming oriented) linux user.
Nvidia simply does not care about that and it doesn't seem like it will change anytime soon.
That's not as true as it's been : they've published kernel modules as opensource. It's clearly not perfect nor comparable to what AMD or Intel do/did, but it's way better than when Linus raised that finger ;)
