Who does? Really, who today uses a mouse based on a technology that went
out of production some 15 years ago and uses a connector that is absent on
most computers (and all laptops AFAICT) produced after 2009?

All of this you can do with xrandr on the command line. And of course
the major WMs have their our GUI tools to do the same.

"Works for me" is not a good way to go when one readies a general-purpose
distribution that is to work on any combination of hardware available on the
target platform.

Yes, and you do not need to drink if you're not thirsty, and you do not
need to drive your car if you do not need to go anywhere.

Which means you do *not* need xorg.conf since Xorg was made capable of
self-configuring on most hardware. I agree. So what? It still holds that
"Not having to login as root to manually configure Xorg just to change video
card or monitor was one of the best and most wanted improvements in Linux in
the past 10 years."

I never argued in udev's favour.
