 The subject is considered controversial among Nix users and developers in terms of design, development processes, and community governance.
 In particular:

  Examples include the notion of a global [flake registry], the [impossibility of parameterising flakes](https://github.com/NixOS/nix/issues/2861), and the [new command line interface and flakes being closely tied to each other](https://discourse.nixos.org/t/2023-03-06-nix-team-meeting-minutes-38/26056#cli-stabilisation-announcement-draft-4).
