Not sure what you're getting at, type input/output functions are no different than other functions. Historically I beleive the issue was that languages couldn't handle the "cstring" type because it was special. As of recent releases that's not a problem anymore (though pl/pgsql still doesn't understand it for example). Another issue was that there was a special hack to create type input/output functions because of the chicken/egg issue of type creation. With explicit shell types this is fixed also (in -HEAD). AIUI, pl/java can do it. For the others I just don't think people have really tried...
