Yes, and it isn't the only problem.

I think the continuous churn of versions accelerates this disregard for supply chain. I complained a while back that I couldn't even keep a single version of Python around before end-of-life for many of the projects I work on these days. Not being able to get security updates without changing major versions of a language is a bit problematic, and maybe my use cases are far outside the norm.

But it seems that there's a common view that if there's not continually new things to learn in a programming language, that users will abandon it, or something. The same idea seems to have infected many libraries.

No, it's absolutely not the same.

Node is on another level though.

It's cause they have no standard library.
