Agreed. I was mostly trying to give the briefest overview I could for a hn comment.

I don't love spring, but I've seen the benefits from having a well-organized, declarative graph of the top-level objects (i.e. the core objects that live for the entire process lifetime). It provides a clear pattern for how to add new code to a large, growing codebase. Without such a structure, devs end up tacking new code on in arbitrary ways.
