This is because of how `orgtbl-to-generic' is implemented. It is taking
pieces from the full ox.el exporter, hard-coding certain things. For
example, it always removes special table lines:

    ;; Since we are going to export using a low-level mechanism,
    ;; ignore special column and special rows manually.

ox.el used to do the same recently, until I added a feature to keep
special lines in tables during export (for ox-org purposes).
