Counterpoint: This no longer matters because we are not going back to hand-writing these functions. These patterns were designed to make code easier for humans to read and write, but that is no longer the primary way software is built.
Counterpoint: as long as context don't rot or it's less effective that starts maintaining repetitions only slightly different. Also
> we are not going back to hand-writing these functions
do you really think there isn't a good chunk, if not the majority outside some bubbles, of developers that still hand code? Crazy to hear, I bet you're not a programmer
Code structure still matters for cost effectiveness and performance over time
