Hi, you are right, this really was a flaw of previous version.
But Vova already pointed to it and it is already fixed.

       /**
	 * Dump the content of a port to a given Lua stack.
	 * When is_flat == true is specified, the data is dumped
	 * directly to Lua stack, item-by-item. Otherwise, a
	 * result table is created.
	 */
	void (*dump_lua)(struct port *port, struct lua_State *L, bool is_flat);
	
       /**
	 * Get the content of a port as a msgpack data.
	 * The lifecycle of the returned value is
	 * implementation-specific: it may either be returned
	 * directly from the port, in which case the data will
	 * stay alive as long as the port is alive, or it may be
	 * allocated on the fiber()->gc, in which case the caller
	 * is responsible for cleaning up.
	 **/
	const char *(*get_msgpack)(struct port *port, uint32_t *size);
