If additional output spaces are needed, please comment here. If they only show up on a full run, it may relate to our plans to compute-on-the-fly to generate files that are cheap to create but expensive to store.

Review the `anat` and `minimal` command examples and their listed outputs for dataset ds005747, subject `sub-011`. The issue asks for feedback about additional output spaces, but does not identify a code entry point or a specific change; completion would require an agreed output-space requirement before implementation can be defined.
