I think that's a good point, never thought about it like that. I like the abstraction level that Spring Boot brings, but working with a principal engineer who was very into AOP on my previous team was a huge pain. Like you and GP said, AOP absolutely destroys readability. Current team has code split into a million xyz-common libraries, which isn't my preference, but I can still click through to see the source of the library. I will never get what AOP truly improves on
