As Russ points out, the current approach of pulling the latest leads to a situation where a package managers can be quite sloppy. For example, a package may have a stated dependency A@1.1.2. But because everyone is pulling the latest, it may turn out that the package actually no longer works with that version of A anymore. The vgo approach will encourage package managers to update their dependency versions to what they have actually tested with, which is very useful information for consumers of the package.
