This is begging for problems. At some point, an user will start to notice weird behaviour he cannot explain from, let's say, the exporter, because he will have completely forgotten about one totally hidden drawer setting export options. I don't think anything should be made totally invisible. There should always be visual clues for such things. PROPERTIES drawer is as hidden as it can decently be. Since its contents are mostly for Org internals, the average user is, usually, not supposed to expand it. If you often need to have a look at some properties, you may use column view instead.
