3D OBJ Import scaling and scripting (24.2.0.38 Win beta)

I'm looking at the scaling of imported OBJs. Why is there a units dropdown? Everything in AE is in pixels, making a units setting questionable. The OBJs seem very large; as I see it, each unit in the OBJ file is 512 pixels in After Effects at 1 meter units and 100%? That's correct & going to be the scaling going forward? Very computer-y and kind of spoils the point of having a units setting. (I see Model scaling and Transform scale are separate, so there are 3 different levels of scaling present.) I'll suppress the Model Settings dialog during scripting; presumably at some point those settings should be scriptable. 

Bug: the Advanced 3D renderer usage warning appears even if it has already been selected by a script.
