The grand-parent and parent are not involved in an active transfer process. They may not agree that the resource in question should be removed, or the grand-parent may have shrunk these resources in error.

If the removed resources re improperly removed, accepting the remaining resources does not help them.

I don't think this is an error case that we are trying to work out, here.  If we are trying to address that, we have a whole lot more solution space to explore.

Ironically, and no one has mentioned this much, but the CP says if a certificate's resources are reduced, the certificate with the original set is revoked.  

(Then a new certificate with the reduced set is issued with the same key.  I think that's weird.  There are people who think it is weird that I think it is weird.  :-)  )

I wonder sometimes if evaluating a ROA EE cert would find the new reduced certificate in the cache first or the issuing original certificate on the CRL first.
