The decision if an edit is a conflict or not is done in MediaWiki core and doesn't have anything to do with the extension. The task is to understand what information core provides about the conflict. Is it even possible for the extension to understand if a conflict can automatically be resolved, and how?
What we would need is a decision like "two conflicting edits have been made, both adding new text at the exact same position, without touching any existing text". Is this possible?
