The comment thread sparked a few new questions for me.

That will likely soon stop working because steam-run is no longer a grab bag for literally every library out there.

What recently changed with steam-run?

Is using pkgs.appimageTools.defaultFhsEnvArgs with pkgs.buildFHSUserEnv a suitable alternative?

   #!/usr/bin/env nix-shell

   { pkgs ? import <nixpkgs> { } }:

  (
    let base = pkgs.appimageTools.defaultFhsEnvArgs; in
    pkgs.buildFHSUserEnv (base // {
      name = "FHS";
      targetPkgs = pkgs: (with pkgs; [
        /* add additional packages here e.g */
        pcre
        tzdata
      ]);
      runScript = "bash";
      extraOutputsToInstall = [ "dev" ];
    })
  ).env
