'3.5' is an API label. So users should just upgrade. There is no reason to stick with R 3.5.*. Not speaking for Michael, but I don't think aims to supply over 4,000 packages for multiple Ubuntu release _and_ multiple R versions. In short, when you opt into the PPAs, you also opt into the corresponding _current_ R release.
