Awesome, pushed as b417dde293080184dae9098e408849a237903a84.

That comes from commit 37861f6c293d7ed1033050b2b0597885ba65186f.  The
motivation was to ensure that substitutes for these intermediate
packages would be available on the ci.guix front-end node.  Failing to
do that, Cuirass would not attempt fetch them from build nodes on the
front-end node.

Sorry that this caused a false alarm!

Thanks,
