It wouldn't even have to change the API.

The final parameter to 'netsnmp_table_container_register' is currently
a boolean flag to control whether rows should be grouped or not.
If this was declared as a more general 'flags' parameter, with flag
definitions such as:

        #define  NS_ARRAY_FLAG_GROUPROWS        0x01
        #define  NS_ARRAY_FLAG_NOAUTOCREATE     0x02

then
     netsnmp_table_container_register( ...., 1 );

would still mean exactly the same as it does now.
We'd just be adding the possibility of:

                /* NS_ARRAY_FLAG_GROUPROWS | NS_ARRAY_FLAG_NOAUTOCREATE */
     netsnmp_table_container_register( ...., 3 );
