It would be nice to have =E2=80=98guix publish=E2=80=99 publish such URLs, =
but there=E2=80=99s
currently no RPC to query a store item by hash.

Alternately, we could have a tool that produces the files to be
published statically (by traversing the package DAG and collecting
=E2=80=98origin=E2=80=99s, for instance.)
