It seems much more likely to me that the use wants to mark a particular
*operation* as a safe, rather than an entire web service. It is also
unclear to me why the "input" to this process should be a SOAP/HTTP POST

Here's what I was expecting: There is an intermediary which maps from,
let's say, the MQSeries/SOAP world to the HTTP/SOAP world. It would be
able to bidirectionally transcode MQSeries/SOAP<->HTTP/SOAP, selecting
the right method based upon something in the message. Ideally, client
side SOAP toolkits would have some mechanism for putting the "something"
in the message.

Why would a user want both a POST and a GET interface to their service?
If the GET binding is complete then a GET interface should be
