Yes, that'd be good in anyway, no matter whether we reduce the targeted devices
of supplements or not.

But, one thing to be noted is that you'll still need to reboot the system to
allow nvidia driver to be loaded.

Strictly speaking, it's no "regression".  Then user will get the very same
driver as Leap 42.2.  But 4.9 drivers in general contain more fixes than 4.4
drivers especially for the recent hardwares, so it's rather "user doesn't
receive a fix".

Right.
