The Codex documentation for threaded comments actually includes this script, hence a majority of the themes have it.

Perhaps, interesting to note the snippet is used in about a dozen themes:<br><br>-- Google ... site:<a href="http://themes.trac.wordpress.org/" target="_blank">http://themes.trac.wordpress.org/</a> "'comments.php' == basename($_SERVER['SCRIPT_FILENAME'])"<br>

Basically, the code is ultimately irrelevant. There's no security
issue though.<br>

It's good to point it out to theme devs that they don't need it.<div><div></div><div><br>

<div>The use-case mentioned is completely different from what
Mark's post is about. the snippet mentioned prevents direct

</div>
<div>Speaking from a technical point of view (and not one of
knowing what the exact theme review guidelines are):</div>
<div>Having that in there is pointless, but having it in there is
not a problem either. It's just extra code being run, it's never
going to prevent a problem, nor create one (Well, unless the
theme is doing strange things in the comments template - like
writing files or something - things that that file should never
do). </div>
<div>So the guidelines are suggesting removal of a useless piece
of code. No need to require it's removal, it's something like
doing this: if ( false ) {run_some_code();} - it's code thats
never going to be of use.. Only thing removing it does it make
people more aware of what the PHP is actually doing..</div>
<div><br>
</div>
<div>As for using $pagenow/wp_die(), it's not needed, nor would it
be available in that case either (direct access of the file). If
the comments template is included, the theme is asking/WordPress
is asking to output the comments... bit of a no-brainer that it
wouldn't need to check the current templating action.</div>

I can't say that I agree that it's a security risk; it's a
conditional, not an input/output.
<div><br>
</div>
<div>However, I'm not sure it's really *needed*. What is the
inherent risk of loading comments.php directly?</div>
<div><br>
</div>
<div>If it *is* needed, what about using $pagenow instead (I
assume it's available in the front-end)? e.g.:</div>
<div><br>
</div>
<blockquote style="margin:0pt 0pt 0pt 40px;border:medium none;padding:0px">
<div>global $pagenow;</div>
<div>if ( 'comments.php' = $pagenow ) {}</div>

<div>Also, might it be worthwhile to use wp_die() instead of
die()?</div>
