Here's the thing: there has never been a lack of people who have declared this problem as solved in the 20 or so years since Python started Poking its way into my professional life. (And for about 12-13 years before that I could gladly ignore it since nobody did much of anything in it). People have said this since the days of the Blackberry.
Multiple times people have explained why they think whatever they are madly in love with now is the definitive solution. And none of those times, over those couple of decades did it turn out to be true.
I understand that you are enthusiastic about things. I get it. But perhaps you might understand that some people actually need to see things stick before they declare a winner? I'm not big on wishful thinking.
I would take a look at uv adoption. That's what makes it different. It nails everything that all the other tools have done and it does it fast. So it's been what people have been using for a while now. Even poetry never seemed to get this ubiquitous of support.
I'm not saying uv isn't catching on. I'm saying most Python software still doesn't use it and for meaningfully complete adoption to happen, a solution has to be the default solution, preferably included in the standard distributions of the language.
