It behooves nvidia's Linux division to be conservative when it comes to driver development. Things change fast in the OSS community, and you never know when someone is going to pull a TTM->GEM. It's best to have reasonable assurance that something is going to stick around before you invest the manpower into supporting it, lest you have to report to the bigwigs that you worked 3-6 months to support something, and ended up having to throw it away because a maintainer decided he liked a certain approach better. Incidentally, that seems to have happened here to a small degree.
