It's funny, when it s not the devs, what you describe sounds strangely exactly like what many ivory tower CTO are like, "researching" useless shiny craps by reading some headline like "google does monorepos" and coming back saying "but you devs are just mindless morons, look at google they do monorepo, you should have the curiosity to merge all our github stuff into one giant repo".
Yes yes boss, we're on it.
