90% of the CRs I've ever gotten have been "artisanal" just because nitpicking superficial nonsense is easier than meaningful critique, and even when the code is perfectly fine it looks more productive from a managers perspective if you're nitpicking a function name than if you just respond with lgtm.

Yeah that's what I understood them to mean from "like when in the office people have been spending weeks on optimizing code... just to have the exact same output, exact same time, but now "nicer"." There does come such a time either way when the juice isn't worth the squeeze so to speak in terms of optimization of code.
