Why can't I add a shared library to a managed user?

This has been discussed plenty in the feature request that is linked above. If you wish to discuss further please post there. I am closing this.

Allow managed users to have access to shared content

I have a managed user for my child. I'd like to be able to allow that user to see specific shared libraries from my friends who have lots of kid appropriate content.   I don't see this as a problem since a managed user is really just a view into the primary users account and doesn't exist outside the home environment.
