Commit 00e057bf44 (#4727) simplified
node-wrapper to a one-line wrapper script for performance. Copying
the binary was proposed and rejected because node finds some of its
modules relative to its own path. But a symlink doesn’t have that
issue, as you can verify with
node -e 'console.log(require.resolve.paths("foo"))'
(To find its own path, node uses `process.execPath`, which resolves
symlinks, and there’s no plausible reason for that behavior to change.
