Hi Jiewen,<br /><br />I agree with your proposal and implemented the changes you proposed here:&nbsp;<a href="https://github.com/kuqin12/mu_basecore/tree/personal/kuqin/var_check">kuqin12/mu_basecore at personal/kuqin/var_check (github.com)</a>. Could you please take a look?<br /><br />Both traditional and standalone instances are tested on our platforms internally, which rendered no issues on compilability or functionality.<br /><br />Regards,<br />Kun
