Shader Complexity in FR

Hi, this is kind of a following of this prior question:

In FR mode there is no apparent way to reduce shader complexity if i follow the same reasoning as using DR, if i put a shader with just a color node attached to the Base Color hatch onto a static mesh the shader complexity is still red.

So i do understand that the shader complexity is expected to increase as explained, but how then do we judge the shader so we can optimize it if needed?

To my understanding what we have to do is to shift the bar so red is our new baseline instead of green and work so we mantain shaders in a very nice dark red, right?

Thanks for any comment
