Just a guess, but probably because you'd have to delete 'both' libraries and then install 'two' libraries and make sure you got it right. (On a library upgrade I mean.) With symlinks, you just switch the 'real' one and the symlink still applies. Not really sure though. Hard links can't (or couldn't - not sure if it's still true) span filesystems either - doesn't apply to /lib but that'd be a good reason to use symlinks elsewhere.
