That's a different case (and I agree).  I don't think SPF or ADSP/DKIM results 
should cause receivers to treat DMARC results any particular way.  
Generically, I expect that receivers will look at a basket of policy results 
(including non-authentication related ones like RBL checks) and if any of them 
say to reject/spamfolder/etc the message they'll do the harshest one (absent 
whitelist results).
