If I'm not mistaken though no longer open source Coldcard has a similar feature
It has a feature where using a pin would open another wallet and also one that can crash it
And restarting would only be possible through the seedphrase.
That is much better and appropriate for wallets than a feature that does a complete wipe, and a good decoy wallet has a better chance of you being able to continue your journey. People are simply not good with backups, and if you look how the Graphene feature works it will delete everything even if you accidentally enter the PIN once in a screen that requires your PIN. So imagine you put a very simple duress PIN and one day you space out while being on the passcode screen, and you enter this one and everything on your phone is gone.

Advanced users can create their own advanced features and make adaptations, features that don't have accidental complete loss for average users are not good. Backups help, but many don't have good backups or have never even verified that the seed phrase that they backed up actually works.
Now we are entering a new phase where having hardware wallet is going to become a threat to the security and government agencies, for the case above if the system was transparent enough someone’s personal finance shouldn’t be tempered with Nk the first place the dude is commonly right for deleting through duress pin but however it’s not going to be considered an excuse for the federal agents. I’d like forcing someone to hand over their finance to you and only kidnappers and robbers does that, so does that mean the feds are now robbers in this case. I just hope he wins this case.
If an agent of a government law enforcement agency forcibly asks for someone's wallet password or forces them to open it for the convenience of their investigation, then they cannot be called a robber or a snatcher directly, they may have abused their legal powers. Their actions may be wrong or unconstitutional. But it may not be right to call them robbers. If someone's personal wallet has to be opened, then they can open it accordingly by seeking permission from the court for investigation
You are correct, for some reason people want to use the wrong words for many things in this forum instead of being precise. Even if this was an illegal action by the border police which has not been confirmed yet, it would still not be a robbery.
However, any person certainly has the right to keep his personal property information secret.
This is really not true at the border, you need to check how the law works. They have the power to search everything that you posses, and just because the information you posses is hidden inside a device that does not make it a special case. I am not arguing that it should be this way, but I am describing correctly how it is. Take for example a Bitcoin wallet that is stored on a piece of paper and you go to the border. They have a right to search you if they want to and they will find this paper. If you instead don't use a paper but hide the wallet inside of your phone, do you now think they don't have the same right to search you to find it? That would be an easy loophole and way to get into the country with all kinds of dangerous content, it would not make sense. You can refuse depending on the country, but if there is reasonable suspicion then your rights are less in what you can do and what your options are than if you are just a stranger.
