I'm talking about what I've typically seen, where the designers work in a silo to develop a design system, then send comps to the developers that completely disregard the innate capabilities and extension points of the components they designed, then feel like the developer is being difficult when what they get back isn't a pixel-perfect reproduction of the comp.

I've also been asked to integrate a plugin where the comps directed me to make that plugin look exactly like its competitor. When I pointed out the overrides would last only as long as the plugin didn't change any of the code I monkey patched, I was again being difficult.
