alt Hacker NewsNPM came along in 2010, Javascript was huge before that.
It was only when people wanted a common approach to shipping both in browser and "native" that this glitch happened. I believe a standard library and "batteries" would have abated it entirely or resulted in a slightly less-bad situation. I do think Cargo is a slightly less-bad situation in many ways, and that it can be done better.
Sure. Maybe threshold is bit higher than moderately. But unless your language tries to sabotage itself by making code artifacts uncomposable (a la C/C++ where best way to compose libraries is through shell commands) some package manager will be inevitable.
Batteries also don't help if dependencies don't replace them. Arrayref functionality has been part of Rust std lib for a while now.
