There's other improvements too. Anecdotally I've seen Yarn 2+ install faster than Yarn 1. The UI output is more informative. The workspace behavior has been pretty solid. The "install Yarn 1 globally, Yarn 2+ per-repo" bootstrapping behavior is a bit quirky, but it does make it nice that everyone using the repo is using the same Yarn version for actual execution.

I like the _idea_ of PnP conceptually, but my experience was that there's too many other tools that depend on having `node_modules` on disk for things to work out okay.
