I moved our massive lerna monorepo to yarn v2 with PnP workspaces and cut 20 minutes off our CI time, deploy/build time (typescript) cut dramatically and reduced even our frontend bundle sizes thanks to the new and improved dedupe. It took all of maybe 10hrs but I've already made that back easily. Also checking out branches and syncing takes all of 3s versus the massive link process we used to have to do. Love yarnv2
