I am not sure if this has been asked for before, but I think it would be really useful to have another setting for the locking options (under interact only): (dis)allow page delete.
Currently, it is to easy for another user who is also a doc maker to (accidentally) delete a page, including sub pages. Currently, a doc owner can easily setup that it is only he/she is the one who can change the locking options, preventing table, data or row deletes, but the entire page with everything in it (including the main tables) can be deleted just a bit to easy by any person (who happens to be a maker too) with whom you have shared a doc.
The delete option is so accessible (desktop or mobile), it is almost scary
