Not disagreeing but unfortunately a lot of data sources have different opinions on this. And sometimes categorizations are actually useful indicators to tell what is what.

You can do a lot of duck typing against such a system and it will work as good as your data is without breaking completely when you get bad data. You just loose some features.
