We share passwords as a team. When I share a top level folder with someone and give them access to all subfolders, I need that permission to stick, just like with every other folder permission scheme I have ever seen.

Instead, every single time a new subfolder is added, the sharer has to remember to go and find the parent folder and select "share all subfolders" again and again. This is a guarantee that team members will not have access to the folders they need access to.
