One of the biggest differences is we have the experience of the
randr-1.2 code in the X server and a chipset which is backed my the
manufacturer to design and test on. It also makes sure the design is
actually real-world useful, I've already deployed this modesetting
code in a standalone GL multi-head enviornment using miniglx code.

We also aim to maintain as much compatibility with the current system
as possible, whereas Jon really didn't care.

Also Jon proposed about 10 things, but never an actual API, the things
he proposed are still problems, but they are I believe as do many
others to be orthogonal problems, not the intertwined things that he
believes should be lumped under a single API ala DirectX.

Dave.
