Does the average L7 person architect those services significantly, or just kinda maintain them? It's almost crazy to think about any old AWS employee (granted L7 is up there) conceiving those things, they've had such a massive impact on the ability to build things on the internet.
I'm not sure about those particular services, but in general the ground breaking and foundational things at the FANG and adjacent companies were convinced by people at much lower level than L7. It was a lot of L5-6 folks who then went on to be 7+ many years later.
