I'm one of those people and I went through enough app publishing that I can already tell you that it's very likely it'll get rejected again in future updates.

We went through this song and dance for actual file explorers more times than I can count. It usually "sticks" for a few updates before the rejections start again.

The policy hasn't changed.

It also doesn't change the fact that they demand access to every single personal photo, media item and document on device instead of using an API that allows user to have control over what they share with the app - it's the same behaviour as Facebook, Instagram and other companies showed before the policy was enacted. Instead of respecting the user, they demand the user gives them access to everything with "trust us, we won't do anything bad" attitude while refusing to do better.
