Which could simply mean that they have a larger ratio of developer
resources to work items.

This is certainly not true.  Pretty much any driver team will
"discriminate against less widespread X11-technology use cases".  As
long as you have two or more things you want to do, it is a safe bet
that one of them will have higher priority than the other.  And I think
it is a safe bet that widely used features will tend to have higher
priority than little used features.

There could also be technical reasons why it is easier to maintain
zaphod mode in the nvidia driver.  Maybe their architecture made it easy
to implement proper xrandr support without breaking zaphod.

Or maybe it's just that some of their engineers actually use zaphod and
thus fixes the problems when they show up.
