Having a narHash doesn't mean that we have the other attributes returned by the fetcher (such as lastModified or rev). For instance, $ nix flake metadata github:NixOS/patchelf/7c2f768bf9601268a4e71c2ebe91e2011918a70f Last modified: 2024-01-15 10:51:22 but $ nix flake metadata github:NixOS/patchelf/7c2f768bf9601268a4e71c2ebe91e2011918a70f?narHash=sha256-PPXqKY2hJng4DBVE0I4xshv/vGLUskL7jl53roB8UdU%3D (does not print a "Last modified") The latter only happens if the store path already exists or is substitutable, which made this impure behaviour unpredictable. Fixes #10601.
