I think that it's not just people not knowing about the lifecycle feature, but also that when they start putting data into a bucket they don't know what the lifecycle should be yet. Honestly I think overdoing lifecycle policies is a potentially bigger foot gun than not setting them. If you misuse glacier storage that will really cost you big $$$ quickly! And who wants to be the dev who deleted a bunch of data they shouldn't have?

Lifecycle policies are simple in concept, but it's actually not simple to decide what they should be in many cases.
