Agreed, DI in moderation can be useful. I generally like to target dependencies with I/O so they can be substituted with test doubles to allow the domain logic to be tested with fast, deterministic tests. On the other hand, I’ve seen codebases that go way overboard with SOLID and create unmaintainable messes that are difficult to reason about.
Yeah, that's always the thing. Sometimes it is good to have a strict guideline/structure to prevent a mess but that itself can be the source if the mess. As it n way to complicated with many unnecessary abstraction layers while a simple direct call to a function would also be good enough.
