While we're on the topic: work on minimal-bootstrap in #nixpkgs has actually been picked up again since this thesis was written (October 2025).
Not only that but, as of a few hours ago, the PR implementing the last step of hooking it up to become the actual bootstrap stdenv in Nixpkgs has been merged!
