Thanks for suggesting this improvement.
However, it seems to me like this would be much too specific to add to the module. (Other users might want/need other information.) If you need the language code, it should be simple to just append it to the data-autocomplete-path attribute via some custom code.
Also, this might conceivably break other people’s autocomplete endpoints, so it would be a risky change to make to the module.
