:) I don’t think its ever safe to assume a change won’t break something for someone. When they re-align roads to prevent car accidents, there is always someone confused by the re-alignment who promptly has an accident.
The warning could be displayed on stderr or with syslog. It could be a 3rd field on Reference ID but as you imply, there is always a risk that someone somewhere will be affected by a change.
