I think that's a very narrow view.

It assumes there are only two possibilities, either you live in a "free country" where you can refuse to hand over the key, or you live in a totalitarian state where the police will decide to beat you if they suspect you have crypto software, and will keep doing so no matter what you say.

There is a lot of middle ground there. For example in the UK, I believe you are legally required to provide the decryption password. But I don't think the police there would be likely to beat you if they think you may have a hidden container. They could argue that they believe you do, and you would respond with "prove it!", and I doubt it would go any further (unless they had some evidence that you specifically were using hidden containers).

There is value in hidden containers in some circumstances. It's disappointing to see the cryptsetup maintainers take this position.
