At the user level, Setting a Timestamp for date created and modified is pretty standard procedure. Additionally a user created and modified. But at the developer level, I doubt FM would bother with this as most (not all) FM development tends to be done by one person. Unfortunately FM is primarily a End User market not a developer tool, so I doubt multiple developer auditing would be at the top of their list. It would also add a lot of baggage if it had to be tracked by each component.
