I have reviewed the proposed changes to confirm their accuracy, and have considered whether similar changes are warranted in the other METplus repositories, and I believe these same changes should be made across all METplus repositories. I see you said you'd take care of the MET develop branch (thanks!). I'll ensure these changes get made in the other repositories. I approve this request.
