PDM also supports centralized package cache like [pnpm] while still keeping project's dependencies isolated.

I don't see why it is a problem, node.js also has node_modules in the project. And __pypackages__ is created with a .gitignore file so you won't commit it accidentally.

Why is node doing bad things a justification for other package managers doing bad things?

I'm not following why storing project scoped things at the project level is a bad thing.
