Custom lighting models (and .usf) support in plugins needed. Is Epic planing to improve plugins?

Apart from custom shaders, I wish the already existing shading models would be exposed a little better.
Just recently changed the diffuse model from Lambert to Oren-Nayar.
Only one line had to be commented out and another comment removed in ShaderModels.usf
In my opinion, the visuals have improved by 200%

If that would be accessible via a material parameter, it would be awesome

I just tried that and, boy, did the results not look great.
