In particular, this means two interesting things: You can write plugins that Yarn will load at runtime, and that will be able to access the true dependency tree as Yarn sees it; this allows you to easily build tools such as Lerna, Femto, Patch-Package, You can have a dependency on the Yarn core itself and instantiate the classes yourself (note that this part is still a bit experimental as we figure out the best way to include the builtin plugins when operating under this mode). Yarn Workspaces is a feature that allows users to install dependencies from multiple package.json files in subfolders of a single root package.json file, all in one go. Starting from Yarn 2 we now keep track of the individual dependency trees for each package that lists postinstall scripts, and only run them when those dependency trees changed in some way: Yarn 2 now allows you to specify whether a build script should run or not on a per-package basis. Alternative ways to code something like a table within a table? Classic is simplier and works out of the box.

Working with workspaces brings its own bag of problems, and scalable releases may be one of the largest one. To give you an idea, we've built a typescript plugin which will automatically add the relevant @types/ packages each time you run yarn add.
