URL to last message in thread list for forum guests

[SAS1024]

In thread list for registered user there is a URL to last message (located on the date information) in the Last Message column.
But if I not logged in, this URL is disappears.
I looked into thread_list_item template and found condition

{xen:if '{$visitor.user_id}', ' href="{xen:link posts, $thread.lastPostInfo}" title="{xen:phrase go_to_last_message}"'}

But why ?
Why forum guests can't go to the last message in thread ? May be it's a mistake?

I have moved this from bug reports as it is as designed.

It somewhat relates to the duplicate link element (which requires a 301 for redirection and thus may be hit by a search engine). You're free to change this on your site if you prefer.
