Why does bumblebee/Nvidia installation involve so many more steps in openSUSE?

I’ve been using various linux distributions for several years, but I still consider myself somewhat of a noob. Installing bumblebee in Leap (or even the older versions for that matter) is a relatively lengthy process compared to some other distros. I spent a little while messing around with Arch a few years ago (as an example), and that was probably the easiest and simplest bumblebee install I’ve ever done. Mageia has a pretty simple installation as well, just install bumblebee and the Nvidia driver and you’re done. So, why are all the extra configurations needed in openSUSE?
