I've tried this with different users. Nothing happens. After I set the checkbox and save it, I get the message "Changes saved". But if I edit the user again, the checkbox disappears.

How long a username change is public for and visible to everyone is controlled by the option usernameChangeRecentLimit. By default, the username change is publicly visible for 30 days.
If you prefer username changes not to be visible publicly to others at all then you can change this limit to 0.
