See [my comment] on the Nix PR to restore the previous behaviour for why I believe we should remove this for the next release. The PR should still be backported to stable releases to avoid making breaking changes to their semantics. [my comment]: <https://github.com/NixOS/nix/pull/13741#issuecomment-3180851635> Fixing this across supported Lix versions is required for Nixpkgs to update toml11, which is a blocker for the CMake 4 update.
