I see; that's L3, L4, and L5 progression in a nutshell at Google - although leaving L3s alone doesn't _guarantee_ something will go wrong, it was more that there was no way for them to figure out optimal solutions without help thanks to the sheer complexity of Google.
I'd say the same held true at Amazon but I was in groups which were, at the time, at the periphery of the company's engineering efforts - we didn't have any associated principals to talk to, and maybe one SDE3/L6 to 10 SDE2/L5s mixed with SDE1/L4s.
