However, it appears that this discussion is academic, because HFS+'s implementation of exchangedata actually returns an error if one of the files is hardlinked.
Huh? If I have file A hard linked with B and I "atomically" replace A (i.e. write A.new, move A.new to A) then I will break the link between A and B. That's the issue here, and that's certainly what happens in the scenario I just described :-). No HFS+ errors here.
