Does that mean when we get a package from an agency, we cannot send the package back, only individual files? If so, this is an irritating limitation.

I know this is a rather late response but I think you should still be able to send Return Packages. Otherwise the package system would be a bit pointless.
As the project packages are something of a project management tool, it makes sense that SDL should exclude their creation from lower level versions of the software.
