This seems really weird and uncomfortable. From the naming I would expect it to be a boolean function and I'm struggling to understand when it would be useful to report multiple endpoints on a widget (edge widgets normally being single objects). The whole counting thing is mainly a combination of debugging and an artefact of the implementation. What's the motivation here?
