I wouldn’t say it’s bogus, and there definitely wasn’t any malicious intention behind it, it’s just that finding a name for such a property is super difficult. As I’ve written above, it’s about having fine-grained control over the data (object) constructors. It turns out most words synonymous to “type”, “kind”, “category” etc. (as understood in the wide sense) are already taken by mathematical / programming concepts. We will, however, change the name, as it causes way too much confusion :).
