Yarn 4.0
Anecdotally, it seems like a lot of Yarn adoption is still suck on 1.22.x. Migrating to 2+ appears to be untenable for many teams.I understand that Yarn 2 is essentially a new tool, as there are certain features you simply can't ship while still being compatible with npm, but this hasn't resonated with developers. The initial appeal of Yarn 1 was that you could pretty much drop it into your node project and get much faster install times. `pnpm`, from what I understand, is faster than yarn, while still having that seamless interop w/ npm.
