This has been the behaviour before Nix 2.4. It was dropped in a rewrite
in 759947bf72, allowing the creation of
store paths that aren't considered valid by older Nix versions or other
Nix tooling.
Nix 2.4 didn't ship in NixOS until 22.05, and stdenv.mkDerivation in
nixpkgs drops leading periods since April 2022, so it's unlikely anyone
is relying on the current lax behaviour.
Closes#9091.
