I think option a) is more explicit, which is probably what we generally want to future-proof the time-machine. Fallbacks are okay in the case of the CRAN URL where it’s not necessarily clear when a package tarball moves from the release location to the archive. In the case of Bioconductor URLs it seems that we can afford to be a bit more accurate. -- Ricardo
