I think the point is that you can already do all of that with hand-wired dependency injection. I wrote about an example of that a couple of years ago here: https://jonathan-frere.com/posts/how-i-do-dependency-injecti...

This has the advantage that you don't need an extra framework/dependency to handle DI, and it means that dependencies are usually much easier to trace (because you've literally got all the code in your project, no metaprogramming or reflection required). There are limits to this style of DI, but in practice I've not reached those limits yet, and I suspect if you do reach those limits, your DI is just too complicated in the first place.
