We agree.  And the underlying design is perfectly able to cope with it.
I haven't checked, but it's even possible that package.el already
handles it correctly if/when the `archive-contents` file contains
various different versions of the same package.

IOW it might be a simple matter of adjusting the scripts that build
the archive(s).
