Is there an "all" option for language detection?

It seems that we have to always specify a value for "languages" in order to achieve language detection.

...
         "properties": {
            "text": {
               "type": "langdetect",
               "languages" : [ "en", "de", "fr" ]
            }
         }
...

We have a very varied data set in many languages and indexing is also not time sensitive, assuming this would be a performance issue. We'd like to know if there is an "all" or similar option for language detection, so we don't have to specify the complete list of languages here.
