I'd consider a lot of spring annotations "black magic" , because you can't simply go to definition and see how/what they do.

Spring's annotations arguably are black magic, but while Spring offers DI, DI is not Spring, and honestly something like Guice is a lot easier to follow since it only does annotation-based DI and not a bunch of other stuff.

You... literally can? Yeah, you may have to grep for the annotation's name, but it's not like it's hidden/closed source/whatever.

grep for annotations...

That mentality is how you get death by a thousand cuts.

Cognitive load matters.
