I know this is an old thread, but this caught my attention. Would it not be 
possible to come up with a tool with which a developer could somehow use 
the old cert as the authority for the new one? After all, the developer is 
the only one with access to the private key, so a new cert could be 
"signed" by the old one just as an .apk file is signed.
