I was really thinking of something that behaves more like a symlink
within the FS. What you describe here is indeed a good implementation
for a hard link, but then you can't track HEAD with it if you put the
NodeChangeID of the target in.

Indeed. But it's not very useful for implementing modules, /precisely/
because you can't track HEAD. That's a must.
