You should keep in mind that tgc where forced to start with 3d commands Before they feelt they where ready for it by public demand.
So dont have to high hopes to have all awesome 3d commands anytime soon.
The shader support is more then enough to make a decent game at this state,you simply have to write them your self.
any Changes tgc makes with added commands is a slow process to test that they work on all platforms.
You Always workaround limitations in an programming language until they support wath you nead.
Any 3d is a abyss filled with lava on mobiles with alot of limitations.
I suggest you do small 3d games that are simple to see wath workarounds you would nead to do in an larger Project.
And a great way to learn shaders on mobiles.
