For context: this doesn't work on virtually every Windows machine. See #7052 for one.

fs.realpathSync is really not very useful because it just points to the original directory. We may well just use the original one, then.

I don't understand, how do we test for our symlinked dir support now?

[Josh-Cena]

How is fs.realpathSync testing anything in practice, though? It always evaluates to "_dogfooding/_docs tests" on machines that support it. On machines that don't support symlinks (i.e. all Windows machines), it always causes an obscure error that I have to teach them to fix. Previously when we had resolve.symlinks: false for Webpack, it seems more worthwhile to test, but now, it's simply not an API of ours anymore, more like a user-land workaround.
