// Originally this code bypassed authorization checks if a contract was deferring only actions to itself.
// The idea was that the code could already do whatever the deferred transaction could do, so there was no point in checking authorizations.
// But this is not true. The original implementation didn't validate the authorizations on the actions which allowed for privilege escalation.
// It would make it possible to bill RAM to some unrelated account.
// Furthermore, even if the authorizations were forced to be a subset of the current action's authorizations, it would still violate the expectations
// of the signers of the original transaction, because the deferred transaction would allow billing more CPU and network bandwidth than the maximum limit
// specified on the original transaction.
// So, the deferred transaction must always go through the authorization checking if it is not sent by a privileged contract.
// However, the old logic must still be considered because it cannot objectively change until a consensus protocol upgrade.
