`esc_url()` is also filterable via the `clean_url` hook. :)<div><div><br>

be clear I understand the requirements.
<div>

</div>
<div>Is esc_url for home_url a
requirement or recommended? This
page: <a href="http://codex.wordpress.org/Data_Validation" style="font-size:12pt" target="_blank">http://codex.wordpress.org/Data_Validation</a> does
not state explicitly that it is a
requirement.</div>
<div><br>
</div>
<div>So if its a requirement - is it a
must fix requirement or can it be a
fix in next revision requirement?</div>
<div><br>
</div>
<div>Thanks in advance,</div>
