And when the new distro-provided nVidia driver does something garish like, say, break XFCE, then it's easy(ish) to roll it back using distro tools and pin it there. After that, just wait until some other more-functional combination of shakes loose in the distro channel.
When a new nVidia driver shows up that promises a fix but the distro hasn't packaged it yet, then the temptation to just download and run the installer that's on nVidia's website. But using nVidia's special-sauce installer taints the system in ways that distro tools deliberately seek to avoid.
And: Oh, man. I'd almost forgotten about the binary tarballs that were intended to be simply dumped into /, where they'd just tromp on whatever. Sure, it was fast. And for some people, some times, it even worked. Sometimes, it didn't work. Other times, it broke other things that had been working. And it left a mess behind every single time.
A little bit of a mess isn't necessarily devastating on a personal system. But the mess accumulates every time such an unmanaged installation process happens until it eventually overwhelms to the point that even the most functionally-disorganized of people become dysfunctional.
