nh clean --quiet not that quiet?

[xfzv]

% nix-shell -p nix-info --run "nix-info -m"
 - system: `"x86_64-linux"`
 - host os: `Linux 6.18.15, NixOS, 25.11 (Xantusia), 25.11.20260304.fabb8c9`
 - multi-user?: `yes`

% nh --version
nh 4.2.0

I'm using

{
  programs.nh = {
    enable = true;
    clean = {
      enable = true;
      extraArgs = "--keep-since 4d --keep 3 --optimise --quiet";
    };
  };
}

However, even with --quiet, nh-clean.service produces tons of

nh-clean-start[122720]: deleting '/nix/store/<hash>-....'

entries when starting the service, cluttering journalctl output.

% systemctl cat nh-clean | rg ExecStart
ExecStart=/nix/store/hvmzkb8an9migj66lz55xcd84zlpski5-unit-script-nh-clean-start/bin/nh-clean-start

% cat /nix/store/hvmzkb8an9migj66lz55xcd84zlpski5-unit-script-nh-clean-start/bin/nh-clean-start
#!/nix/store/fwr62xmh06l8y8zfgc5m18pfap9b8az0-bash-5.3p3/bin/bash
set -e

exec /nix/store/ggq9i0azscf4lkg17sjnhr6k8y0jlin0-nh-4.2.0/bin/nh clean all --keep-since 4d --keep 3 --optimise --quiet

--quiet is used.

I could use journalctl -T nh-clean-start but I'd like to still see basic info regarding the unit.

Is there any workaround? Or maybe I'm missing something?

Thanks!
