Nixpkgs that need --no-sandbox

Nope thats a configuration option.

Though I just checked the most recent release notes, the attribute I had in mind was not about the sandbox but impure derivations:

Nix 2.8.0 released

New experimental feature: impure derivations . These are derivations that can produce a different result every time they’re built. Here is an example:
stdenv.mkDerivation {
  name = "impure";
  __impure = true; # marks this derivation as impure
  buildCommand = "date > $out";
}
Running nix build twice on this expression will build the derivation twice, producing two different content-addressed store paths. Like fixed-output derivations, impure derivations have access to the network. Only fixed-output derivations and impure derivations can depend on an impure derivation.
