Nico,

Nico,
Panel pressing equipment is notoriously expensive for car manufacturers so the additional lugs probably cover new or future options, that are obviously not fitted to my van. The lug on far right is probably something to do with the two similar shaped lugs above it (also not on Kirivans YouTube video, but don't need removal), where some item is fitted and slots down into the three lugs. The other two lugs on left that do need removal could be for any number of options, if I had to guess something to do with adjacent locking mechanism.
