If you add the new option similar to the stack checker option

     #ifdef CONFIGURE_STACK_CHECKER_ENABLED
       RTEMS_STACK_CHECKER_EXTENSION,
     #endif

then you can either use the application configuration option to enable 
the extension at the recommended position or you can use the extension 
define in your CONFIGURE_INITIAL_EXTENSIONS exactly where you want it.
