Actually, I think the problem is in the code which does the deletion: it
should only do the delete files it positively knows should be deleted,
rather than deleting any files which seem to be out of place.

Once we change the handling of :core in elpa/admin/archive-contents.el
so that it sets up symlinks rather than performing copies, we should at
least be able to make the deletion less dangerous, e.g. by only deleting
symlinks and empty directories (so even if the deletion was erroneous,
no actual file contents was destroyed along the way).

Fabián, any news on this?
