Good afternoon. 

There is a solid consensus in the OSM community to only add language specific names (same for brand and operator tags) if they’re actually in use and verifiable. This does not seem to be the case for the :id and :it tag variants that you added in this changeset. 

What benefits do you see in adding these tags? 

The downside of having such translations in OSM data is that map users with system language in a given language get to see fictional names instead of what's actually on the ground.
