Why remove the added security of a separate PIN

The app was nearly perfect for the average uses, save for adding a select all button rather than having to click one by one.

Why remove the added security of having a separate PIN or requiring Touch ID to unlock the drive? Given that my phone is used by children to play games, I prefer the peace of mind knowing they can’t access personal documents or files if they didn’t know my google drive PIN or have my fingerprint for google drive Touch ID verification. I have zero use for having this app installed now.
