Describe the bug

nix flake check doesn't seem to respect extra-experimental-features in nixConfig.

Steps To Reproduce

  1. Create a flake using an experimental feature (I use pipe-operator)
  2. Put nixConfig.extra-experimental-features = ["pipe-operator"]
  3. nix flake check
  4. See error: 
    $ nix flake check
error: Pipe operator is disabled
       at /nix/store/sh9wrc00k7pv347664ybbf2fkmx2ni7f-source/flake.nix:116:7:
          115|       }) // (self.nixosConfigurations
          116|       |> (nixpkgs.lib.filterAttrs
             |       ^
          117|         (name: value:

Expected behavior

nix flake check runs successfully.

nix --version output

$ nix --version
nix (Lix, like Nix) 2.91.0

Additional context

Perhaps more commands also don't respect nixConfig. More research may be needed.

you are asking lix to parse flake.nix while observing settings it can only obtain by parsing flake.nix first. there's no resolution for this. flakes simply cannot enable features affecting parsing for flake.nix via nixConfig.
