Claudio is trying to extend gloss-latin.ldf, so telling him that the file -- which he wrote himself -- currently works well is not very helpful ;-)
Claudio, please describe precisely what the new option is expected to do, I'll help you write the code. Better yet, open an issue on the GitHub tracker: https://github.com/reutenauer/polyglossia/issues/ so that the discussion takes place in the proper location. Best, Arthur
