Block core/list defined outside any layout handle

Question

What does this definition of a block core/list mean, at the very end of checkout.xml, Magento CE 1.7.0.2:

[...]
        </checkout_onepage_failure>
    <block type="core/list" name="additional.product.info"/>
</layout>

Just a bug?

Answer 1

Seems to be a bug - in Magento 2 this is not there any more.
