I cannot express how painful yarn pnp has been for us. We've been stuck on a relatively pretty old version of Typescript (4.8) because upgrading it with yarn is so difficult. You have to contend with Yarn patching Typescript, and requiring obscure IDE integrations so it all just works. We still can't update, because we can't get Typescript + Yarn PnP + VS Code on macOS to work together. It has been such a massive time sink for us.
I see no reason for anyone to use Yarn. Either use vanilla npm, or use pnpm which doesnt require a mountain of hacks to work.
We've been running TS + PnP + VSCode on MacOS throughout the entire lifetime of Yarn, through versions 1 - 4.
The plugins system has been extremely valuable to us, and the hoisting / peer dependency behavior has been consistently correct, where other package managers have caused bugs.
