Eelco has made several early contributions to NixOS including writing the samba module among other things, but is more or less inactive these days. By my brief inspection, he has not committed to the nixos/ tree since releasing Nix 2.13 in early 2023 and merging a PR to networking tests slightly before that. A lot of these tests/modules are actually unmaintained in practice, so we should update the code to reflect the practical reality so someone can consider picking them up.
