iOS 13 changes a lot about how files work, also internally, so implementing a correct File Provider is going to be quite hard (even the iCloud one doesn't work properly yet in the beta ...). I hope Dropbox and the others follow suit and implement this correctly. Just another example of how files are difficult to get right.
