I would hope so too. I could imagine a requirement on user agents that they 
can only be compliant if they can not only spawn headers but also react on 
the exception mechanism, meaning that a server is able to get an exception. 
I fear that the anti-virus tools don't do that and just send headers. This 
is excluding the choice we want to enable.
