A small test could be:

$ rm -rf test; ls test; mkdir test; touch test/a test/b; cp -il test/a test/b
ls: cannot access test: No such file or directory
cp: overwrite `test/b'? y
cp: cannot create link `test/b': File exists

Thanks for the report.
I agree that the current behavior is undesirable.

How could we change it? (--link (-l) is not specified by POSIX, so we may)
Here are some ways:

However, this behavior has been with us for nearly two decades.
Is it really worth changing now?

Regardless, you can certainly use --force or --remove-destination to avoid
the failure.  Or use --backup to move any existing destination file aside.

Unless someone steps forward to work on this,
I suggest we simply close the issue as "not a big deal",
given that there are plenty of ways to work around the problem.

Given the above, and with no further follow-ups in 6 years,
I'm closing this bug as "wontfix".
Discussion can continue by replying to this thread.
