It is important to keep the version as parsed by `builtins.parseDrvName` monotonic for packages that often switch between stable and unstable versions, for nix-env to be able to update them reliably. Let’s optionally use the version format described by RFC 107: https://github.com/NixOS/rfcs/pull/107 The downside is that it requires fetching more commits to be able to determine the latest tag.
