Looking on computers near me.

A MacBook Air with OS 10.12.6 has two different files, not linked,
but with exactly the same contents.

ls -li compress uncompress
421074 -rwxr-xr-x  1 root  wheel  27680 Jul 14  2017 compress
421907 -rwxr-xr-x  1 root  wheel  27680 Jul 14  2017 uncompress
and cmp -l shows that they are the same.

FreeBSD does use the hard links, and also Linux.
The Linux system is 13 years old, so doesn't disagree with your dozen years.
