At the F2f, I pointed this out when we were talking about removing the "web method" completely and IIRC we agreed to look at it separately.  While it is true that the SOAP binding 2 MEPS only allow GET or POST, it is not true for this in the http binding or potential other bindings.  Notice that my message does not refer to the SOAP binding.

Choosing a generic/constrained operation is an application designers choice and should be made available to them.  I also proposed that this "webMethod" could be used as a default for the http binding's http:method.  I proposed a "useOperationWebMethod" attribute, but in retrospect the interface operation webmethod should be the default for the http binding operation method.

Arguably this is a new "HTTP GET+POST only" binding.   Thus the availability of the web method at the application level provides re-use for them as they can define that PUT and DELETEs are bound to POST.  The alternative is that they would have to specify a binding operation for each interface operation.
