Should we merge SlicerFreeSurfer and SlicerFreeSurferCommands, and move them to the Slicer GitHub organization?
Please see the discussion here for more details.
One thing to consider is that the SlicerFreeSurfer extension doesn't have any external dependencies as far as I'm aware, whereas the SlicerFreeSurferCommands extension depends on FreeSurfer which needs to be installed and configured by the user, takes up about 14 GB of disk space, and can only be installed on Linux/Unix OS (on Windows WSL can be used).
