I had forgotten that you are also building many packages. Given that, an
update to the R guix recipe may break some packages. So all the packages
should probably be tested as part of an R recipe update. Do/did we do
that?

As regards keeping a couple of R versions, if we don't keep the
associated packages it will have limited usefulness, so I withdraw
the suggestion.
