In #2271419: Allow field types, widgets, formatters to specify config dependencies we add content dependency information to entity reference fields when the have default value (if they are referencing content entities).

The current code will remove a content dependency if the field is saved after the content is deleted. It will not change the default value but at runtime EntityReferenceFieldItemList::processDefaultValue() filters out non-existing entities.

This issue will discuss whether this is the correct behaviour. We explored throwing an exception in #2271419: Allow field types, widgets, formatters to specify config dependencies
