Lets keep this simple.

 From the beginning, there were certain policies that were considered 
that I can best summaries with these dialog box:

   -- SSP --

   DOMAIN: __________

   (_) NEVER SIGNED
   (_) ALWAYS SIGNED
        (_) ME ONLY
        (_) 3RD PARTY LIST  [ EDIT LIST ...]
   (_) SOMETIMES SIGNED
        (_) ME ONLY
        (_) 3RD PARTY LIST  [ EDIT LIST ...]

   [ SAVE SSP RECORD ] [ REMOVE SSP RECORD ]

That was deemed too complex, at least the 3rd party portions of it.

So now we have (I think)

   -- ADSP --

   DOMAIN: __________

   (_) ALWAYS SIGNED
        [_] ME ONLY
   (_) SOMETIMES SIGNED
        [_] ME ONLY

   [ SAVE ADSP RECORD ] [ REMOVE ADSP RECORD ]

Any further reduction is not going to help target the market of 
domains that at seeking exclusive DKIM signature usage.
