FileSystem not deleting symlinks

The FileSystem library uses DeleteVisitor and PostorderGuide
(depth-first) to delete a directory and all its children. All its
children? No. Symlinks are protected from deletion:

DeleteVisitor>>visit: aReference
  PostorderGuide
    show: aReference
    to: self
    selecting: [ :entry | entry isSymlink not ]


I didn't find any unit-test or documentation about why symlinks are
excluded from deletion. I don't see any reason. I'm quite sure the
author had a reason to do that but I don't know which one.

Anybody has an idea?

Perhaps a risk of deleting the symlink target instead of the link itself?

IIRC before the VM changes to distinguish symlinks, that was exactly the dangerous situation. If you had a symlink to your home directory in a folder which you deleted from Pharo... bye bye :/
