Yes, I also find it unsafe. However, note that some standard modules do
that too. For example mod_include runs sub-requests from within its
output filters. In my opinion this shouldn't be allowed, because with
the wrong configuration a web-admin could cause the server to go into
recursion. But since mod_include is a standard module, I guess what it
does is considered legal.
