For one thing, those two nodes are so tightly tied together that they might as well be just one node. (Why do you make it so complicated for the artist when they will have to use those anyway?)
For another thing, the output of the giant fragment node is the fragment color. There is no place to inject anything else because you’ve bundled it all into one black box. Texture filtering? Screw you, edit code. Color gradients based on normal, sorry, again, edit code.
So yeah, I guess our definitions of “easier” are just polar opposites… only mine matches the dictionary definition.
