Comment (by gk):

 As I said on IRC you don't want to have just one key baked in. Think about
 losing the key/having it compromised. How are you updating your users? You
 can't sign the MAR files with the new key you are about to bake in. Even
 if that would still work (because you just want to rotate to a new key)
 every user would need to update to that particular version. Let's assume
 you need to get a chemspill release out the week afterwards if you used
 your new key to sign the MAR files a considerable amount of users will
 have a broken update experience as they won't have updated to the version
 with the new signing keys baked in yet.
