Yeah, it seems to be a mystery to everyone. There is an explicit entry in
the debian/changelog of Policy from Ian Jackson about it for version
2.1.1, but all it says is:
* Hard links are forbidden in source packages (they didn't work anyway,
and can't easily be made to work reliably).
This is from when Ian was maintaining dpkg, so presumably he thought
something was broken at the time, but it seems to have been lost in
history. They do obviously work now.

Thanks, that does seem like a good idea.

Thank you for the review! Now applied for the next release of Policy.
