I've usually seen it come up when people try to hash the objects to use as dictionary keys or in sets, and then encounter very hard-to-troubleshoot issues later on. Obviously it's a bit weird to hash a bunch of objects of different types, but it's just one example of the footguns that namedtuples have and why I prefer other approaches.
