> If there are clearly better algorithms, why not refactor npm and add them in experimental flags to npm While node_modules has many flaws, in the current ecosystem all modes have their own pros and cons, and there isn't a "clearly better" algorithm: node_modules has less friction, PnP is sounder, and pnpm's symlinks attempt to be kind of an in-between, offering half the benefits at half the "cost". Like in many computer science things, it's tradeoffs all the way. Part of why Yarn implements all three.
