      HttpTransport API for the secure repo, we need to have access to that
      transport when we initialize the repo, but as things stood that was not
      possible (cabal was initializing repos ahead of time but the transport on
    * For the integration with the nix-local-branch it is important that the Repo
      type remains Serializable. By passing RepoContext rather than a list of
      Repos, we can leave RepoSecure serializable and separately maintain a mapping
      from cabal's Repo type to hackage-security's (stateful) Repository type.
