I don't really disagree, but Python is complicated because the language existed before all of those others for the most part and got quite popular before them too. This means the various use cases for Python got spread about long before the packaging tools really started to try and catch up. It used to be a technical problem.
This means trying to fit all the various use cases for packaging has been like herding cats. It's certainly not a technical problem anymore, the newer ecosystems/languages have figured it out, but it is a community/human problem. Thankfully there is now a small dedicated team that has been working on the problem for years, and progress has been made. For the most part if you stick to a single tool(poetry or rye for example) then most of your problems disappear as long as you stick to their blessed way, whatever it is.
