I can't just *revert* it. Ubuntu 17.04 was released a couple days ago.

If we do add put those .libretro files in a separate package, I just
have to have the new package Break/Replace those Ubuntu packages.
Those Breaks/Replaces can be dropped after Ubuntu 18.04 LTS.

I apologize for not being clear. The appstream metadata must be
shipped in the package that contains the file, because the whole point
of appstream metadata is that it identifies the package that needs to
be installed.

appstream is not just a GNOME thing. It is also used by Plasma
Discover (included in a typical KDE Desktop).

This is a cropped picture of what it looks like. This is at the bottom
of the GNOME Games details page in GNOME Software on Ubuntu 17.04:

All a user has to do is check the box to get that support or uncheck
the box to uninstall the addon.

Thanks,
