Actually, whatever you want, it needs fixing.

I vividly remember being quite pissed by Git replacing a symbolic link in my working directory with a directory, and instead of updating the files which were technically outside of the repository, Git populated that newly created directory.

However, please note that Junio's patch affects git-add, AFAIR, not git-update-index.
