Now I understand from here what exactly you are talking about. Your thoughts make sense – a kinematic character controller, 3D lights and shadows, and camera functions are pretty basic things with established standard practices. As Defold grows for developing 3D games, we’ll need more resources on getting a 3D game set up, akin to 2D game materials.
One challenge is that 3D in Defold is in a bit of flux currently, as the developers are putting some emphasis into developing it. 
Resources could quickly become dated. The camera module and its relationship to the render script changed not long ago.
My honest feeling is that you’re early for the show. Grab a seat, and welcome.
