I'm late to my own roadmap here, but: Progress: • Symlinks are in Pants now! There's a couple of friction points, but the ground is laid and they can be catptured/re-materialized • immutably symlinking "large" files/dirs is almost landed Plan: • https://github.com/pantsbuild/pants/issues/17372 • https://github.com/pantsbuild/pants/issues/17540 • I might finally try and make a generic copyright formatter
