I would be in favor of anything that helps to reduce duplication.
I cannot locate a copy of Jonathon's suggestion and I am unclear about
the detail of what is being proposed here. If my guess is correct, you
are suggesting removing (archiving) the downloadable files on the wiki
and replacing them with links to the published files on ODF Authors,
which is the source for those same files uploaded to the wiki. This
would seem to be a very sensible approach, but there are 2 caveats:
1. There might be some restriction on linking files/images on external
sites to our wiki, see: https://wiki.documentfoundation.org/Help:Editing
Even if such a restriction exists, it might be possible for infra to
configure an exception for the ODF Authors Plone instance running on our
servers.
2. Not all native language projects use ODF Authors as their
documentation work space, so this might not be a suitable option for
those projects. I would recommend speaking with Sophie on this point.
There may well be other aspects I have overlooked here.
