While the filesystem might have such a folder, the intended way to
solve the use-cases you are mentioning above is the
content-picking/sharing infrastructure.

Well, the confinement approach basically says: There is no content on
the phone that is not owned by an app. With that, the pictures folder
would be owned by the default Gallery application and thus,
confinement rules would apply again.

I'm trying to understand this app's concrete use-case better to
propose a way forward.
