Yes, its 2-dimensionalness is hard coded.  For example, in md_array.h you see:

struct _md_array {
     const char *name;
     filter_list *filter_list;
     struct {
         indexer_t *indexer;
         const char *type;
         int alloc_sz;
     } d1;
     struct {
         indexer_t *indexer;
         const char *type;
         int alloc_sz;
     } d2;
     dataset_opt opts;
     struct _md_array_node *array;
};

So to extend it, you might have to start there and add more indexing dimensions.
