i think it is better to write down a how to install it for new users if you want so much to help them than have it preinstalled.
and by the way a new user with no knowledge of the power of console should stay away and connect via ftp/sftp/smb.
a user that wants to learn will find a way to install it and he will learn also in the process of installing it. what will he learn if it is preinstalled? how to use it? that is not the power of console.
kodi file manager can access all file system. just add / as a source.
