I am missing some good advice on that website like

• that old packages are insecure and you are downloading all of the old and insecure dependencies
• that things might not work at all and require also older versions of nix itself or your kernel

To demonstrate that I just grabbed the oldest version of firefox and it immediately broke:

 ▶ command nix-shell -p firefox -I nixpkgs=https://github.com/NixOS/nixpkgs/archive/c9982118fc1be9bbe87f3ed00cd248e4c4c4dfc6.tar.gz
error: undefined variable 'pkgs'

       at «string»:1:42:

            1| {...}@args: with import <nixpkgs> args; (pkgs.runCommandCC or pkgs.runCommand) "shell" { buildInputs = [ (firefox) ]; } ""
             |                                          ^

Also installing old versions via nix-env isn't a good advice because nix-env is really great in being forgotten and doing the wrong thing and leaving people with old packages without them actively seeing it anymore.

Also, I appreciate the work, but it's too new at the moment. I also do agree with Sandro's points
