Is there an officially sounding document with "open resolver considered 
harmful" or alike?

It's not trivial to deal with a corporate client with an open resolver. 
You can't really shut them off, can't filter them etc. Googling for <open 
resolver considered harmful> yields nothing I can point customers to.

<http://www.ietf.org/rfc/rfc5358.txt> is the closest I can find?
