Well, was it "explained" ? They both raised and stressed a hypothetical issue: That "there might be siutations where a partial upgrade breaks" We don't actually know whether this holds.

I think this is a dissservice to our users. Consider another data point. It so happens that we have informal backports for both Debian and Ubuntu at all the CRAN mirrors: https://cloud.r-project.org/bin/linux/debian/ https://cloud.r-project.org/bin/linux/ubuntu/README.html I am not aware of anything breaking there either. So I think this is blown out of proportion regarding the _potential_ partial upgrade issue. We just don't know if it really applies.
