We have sensible reasons to suggest this in both the cases : simple and complex.

If GCP is composed of 10-30 services (hypothetically) then keeping 5-10 employees whose job is ensure mega deletes are safe is not too much of a cost.

If GCP is composed of 500 services, then it is all the more important to have humans in the loop so ensure correct behaviour so that complex interacting services don't take a wrong action.
