The "Javascript ecosystem" on my personal experience seems to prefeer installing everything in the global environment "for ease of use convenience" and then they wonder how did a random deprecated and vulnerable dependency get inside their sometimes flattened, sometimes nested, non-deterministic dependency chain (I wish the deterministic nested pnpm was the standard...) and (pretend) they did not notice.
That being said, the Javascript ecosystem has standarized tooling to handle that (npx) that Python doesn't (I wish pipx was part of standard pip), they just pick the convenient footgun approach.
