Indeed I have not. In fact I haven't even heard of people doing this until your comment. And that's before unknown app developers coming into the picture. I assume you do this to avoid border phone searches? And you feel the (ostensibly) security-related mechanisms for the rest of the world to be centered around this use case? Meaning the rest of the world should pay the cost to their own security to cater to this flow?
