That's an awfully good point.  One thing this discussion has clarified for 
me is that "Web Services" cover an awful lot of application territory, from
behind the firewall EAI, over-the-web aggregation such as Amy Lewis
described, to the wireless device scenarios I usually bring up.  Clearly
one set of best practices doesn't cover all, and I suspect that the 
granularity issue is much like the synchronous/asych issue -- the better
your connections, the fatter your clients, and the faster your back-ends, 
the more viable  "SOAP as just another RPC mechanism" is.  

I'd just remind people of the converse -- the worse your connections, the 
thinner your clients, and the uglier the back-end processing, the more
important it is to ratchet up the granularity and to consider asynch
messaging  protocols, pipeline processing models, the "spaces"
coordination model, and so on.
