Justin, the edit bot does only what it's told to do, so if at all, you should be mad at the Categorization Project, not at the edit bot.
While I'm only officially leading the location categories for Italy Project, I also try to take care for other Italian categories. I don't think a category "Italy, foundlings" will be any different than a worldwide "illegitimate" or "foundlings" category. There will be many profiles in it, and then? What is the advantage in grouping them? If surnames should be compared, then a category or WikiTree+ might not be the easiest way of doing it. Then I would suggest a spreadsheet that can be sorted by surname, date and location and can do graphics. As much as I know, getting a spreadsheet from WikiTree+ is quite complicated.
As much as I remember discussion in the Italy Project, surnames of foundlings differ quite a lot by region, so a full "Italy, foundlings" category would not really be useful. Maybe a solution could be to make a subcategory "foundlings" for a One Place Study? See answer of Danielle. That would be okay for the team leaders of Italy Project.
