That depends on the culture of each specific organization. Are there top-down engineering decisions? Is there a push for more team autonomy?

My experience is that many organizations have something of a pendulum swinging between those two positions, so the current state of that balance may change over time.

Also: many new developers, when they hear "microservices", will jump straight to "that means I can use any language I want, right?"

(Maybe that's less true in 2023)
