That should answer why it is not used, but i would add that it didn't offer any useful benefit speedwise and under certain setting scenarios it could even slow down things (if you used it with safe texture cache). And it would break stuff too, New Super Mario Bros (spinning coins) didn't work with it.
The spinning coins being broken was a bug, which was fixed eventually. But i agree, there wasn't much to gain by it.
