Fx author (in part) here - replied in a separate comment. I mostly agree with you, but DI offers some ecosystem-wide benefits that may be useful in some environments.
I want to say thanks to your team for open sourcing this library so the community can discuss. It’s ambitious and to me feels like a right size approach to the problem, for all the heartache around DI, it seems like it’s different strokes for different folks but that doesn’t mean we should all be taking a collective shit on the engineers who are trying their best to provide a way to organize service complexity strategically. Well done.
