Yup, that's connected to the Returnpath feedback loop, rather than  
reputation tracking. They're allowing you to sign up for a feedback  
loop for a particular d= value and for either one specific selector or  
all selectors.

When tracking specific issues it may well be useful to get FBL reports  
for just one specific user of a DKIM identity, and being able to key  
on selector seems a good enough way to do that, if a bit of a hack.  
It's not something I'd expect anyone to use normally, though.

I don't believe that Yahoo are using the selector for anything  
reputation related, though, and I wouldn't expect them to do so in  
general. (Not ruling out some ESP-specific hack, if it turned out to  
provide them with useful data, but that would be a private hack rather  
than anything more).

RP or Yahoo might be able to be more authoritative on that.

Cheers,
   Steve
