I've noticed that certain packages never seem to have substitutes available from ci.guix.gnu.org.
This is not about packages that consistently fail to build, like Vigra (LibreOffice) [0], but packages that never seem to be attempted at all, and are not found when searching on the CI results. For example, ncmpcpp has not been built since February 2020: https://ci.guix.gnu.org/search?query=spec%3Aguix-master+system%3Ax86_64-linux+ncmpcpp And Borg has apparently never been built: https://ci.guix.gnu.org/search?query=spec%3Aguix-master+system%3Ax86_64-linux+borg By the way, the dates that are shown in this interface do not display the year (can we fix that?): https://ci.guix.gnu.org/build/2275489/details [0] <https://bugs.gnu.org/40887>
