Thank you Jose, for your 2 decades of relentless work. I have not disparaged any maintainers or their work. I get it from your comments that these projects are in early days of adoption and development.

From my perspective, just because Chris Grainger does data pipelines in production does not prove the project is for everyone. It means it worked out for him.

May be seeing more updates, papers, interviews, podcasts about their usage in production will change things.

For now, my assessment is everything is wonderful till one hits a limitation of these libraries. If it works out, its wonderful, if not its like neither here nor there.

That's precisely my point. Because Chris runs it in production, it doesn't mean the project is production-ready for everyone. And the fact you ran into roadblocks, doesn't mean they are "mostly for hobby" or are "half-baked". Your initial comment lacked this nuance and rushed into generalizations, which I did my best to clarify.
