Dropping this feature would have saved a few transistors without affecting too much the performance in real world apps.
IMHO nVidia reuse the ROP Design (and everything behind) from NV30. In this case the ROP allready can work with 4 pixel/clock.

The ability to write 4 (simple) pixel per clock is not very usefull for games at all. But In the case of CAD applications it should help much more.
