How to disable Nix channels?

[thecaralice]

I manage my system with flakes, so channels sometimes lead to surprising results.
I tried settings nix.channel.enable = false as it is on NixOS but found out that this is not an option.

We don’t have an equivalent option, any PRs to add logic mirroring that from NixOS would be appreciated

The module can be found here: https://github.com/NixOS/nixpkgs/blob/nixos-unstable/nixos/modules/config/nix-channel.nix

Yeah, I'm already working on it!

@Enzime I stumbled upon

nix-darwin/modules/nix/default.nix

Lines 753 to 756 in f7142b8

	(mkIf (config.system.stateVersion > 3) (mkOrder 1200
	[ { darwin-config = "${config.environment.darwinConfig}"; }
	"/nix/var/nix/profiles/per-user/root/channels"
	]))

which is in contrary with what NixOS does. Is it really needed? I'm in favor of mirroring NixOS behavior here, i.e. demote it to mkDefault priority and move this default to the option declaration.
