I don't think it is a major issue for you, unless you are regularly linking and unlinking files. While I haven't studied the code, what I believe it is taking about is that when an archive is first made it will duplicate hard-links, if they exist in the source, unless --no-hard-links is specified.
However, during regression, if the change was the deletion of one of the linked files, it will not relink it, but create the file as a separate file. This is not surprising as finding related linked files is a very hard problem, involving searching the entire archive, each time.
However, these days, hard links are not that common, as most people prefer symbolic links.
Also, ultimately, when you finally expire old archives, both copies of the files will be removed, so it is not that you will lose space long-term.
If you do want to see how common links are on your computer you can run something like:
find / -type f -links +1 -ls
and then try it on the areas that you usual have changes in, e.g. /home.
