Right...though this example shows why it may be worth spelling out  
the assumptions.  The "argument" of a method consists of not just  
the bare entity body in the request, but also any associated *entity  
headers* (as caches must be aware).  So the "understood variation"  
of a response must be (to use your notation):

   Vary: {request-URI}, {method}, {{entity-headers}, {entity-body}}
