It would be nice if there was the ability to delete the default document types in the Document Library (contract, marketing banner, etc.) without them repopulating whenever the server restarts. Right now, you can remove com.liferay.portal.events.AddDefaultDataAction from the property
and achieve this functionality. But the removal of com.liferay.portal.events.AddDefaultDataAction removes other features as well. If there was a property that was created to only disable this feature that would make the accomplishment of this feature more straight forward.
