Maybe... But ignoring the fact this lgel of customisation is unlikely for any normal and most tech people, you'd likely require root to override the core system and password auth I'd imagine. I believe this ends up invalidating what is core functionality for most people - banking, wildvine, etc.
If we're moving into the realm of the ultra paranoid, high security over convenience focused user - sure. In fact I dare say such a user might prefer a Linux phone with physical keyboard, or no phone at all. But if we're talking average iPhone or Android users here, I can't imagine the scenario would change much at gunpoint.

This is HN though...surely there are a lot of people who care about security and have experience using custom roms.

Honestly, even a simple solution would be putting on something like Prey, which is free and easy to use, and using a third party applocker tool. Those two things don't need a custom rom or any other customization.
