Hello everyone. I am sorry that this caused a stir. I've been made aware afterwards that changes across a large area are preferably to be avoided.
That set of changes was proposed on place=town and city, above old_name:it mostly, and name:it where the notion of anachronism can be challenged.
I agree that OSM is not a source to consider, and should have worked differently. This job of adding historical names for the benefit of everyone, culturally, is a first to me,  but it remains my goal as it could benefit the people.

Because a lot of  old books have been made availiable to the public, i'll be able in the near feature to gather that data again with incontestable sources.

This is why I'll agree to put down those changes for now as you read that message.

For replies, I understand and speak French, Italian & english.

Best regards
