Well, because of exactly this. Symlinks that create circular directory
structures are extremely common. Not dangerous in the security
vulnerability sense, dangerous in the "this may not do what you expect and
be very slow and annoying while not doing it" sense.

It smells like a transitional measure, but I don't know for sure. I see
that it was intentional:
lua50 (5.0.2-3) unstable; urgency=low
* Fold in a patch from Reuben Thomas, integrating the signal and error
code from Fedora Core. Thanks Reuben.
* Lintian cleanups (recursive symlink stays, sorry)

I do generally agree that it's not the best idea if there are other
solutions to the same problem, but I can see why one might arrive at this
solution.
