An excellent point.  A Web front-end server should be that - merely the front-end.  Situationally-appropriate 
functional separation is a key architectural principle.

Combine that with the measures outlined in <http://mailman.nanog.org/pipermail/nanog/2010-January/016747.html>, coupled 
with a functionally-separated, bulkheaded DNS infrastructure pictured in <http://files.me.com/roland.dobbins/m4g34u>, 
and one will end up with a much more robust, scalable, and defensible system.
