Why? It is just a file that inherits its stat data and is referenced by a concatenation method of its parent directory. The link will also inherit its stat data from the original parent directory.
For example, it's likely that most filesystems would _not_ allow linking of a named stream anywhere else.
And you might not be able to change the permissions or date on the named stream either, since it may or may not have a separate date/permission thing from the container.You should be able to change the permission and data, but when you change it, you change it for the whole container.
