Came here to suggest something similar while trying to fix an old escape the room that broke in 1.13 (damn selectors not working from command blocks!). Perhaps, for the sake of simplicity, the specialized commands could recognize items from CMI's saveditems by name. So like hasitem:Key1! All we'd have to do is save the item.
