It is a separate parameter because HuC requires GuC to be loaded. It is ok if command submission is not happening through GuC but GuC "has to" be loaded for HuC to function. Guc_submission parameter enables the command submission through GUC. But, guc_loading parameter ensures not only that the GuC is loaded but also that HuC can now function.
