The seized device scenario is starting to get very specific though: in the actual cases it's relevant like the Silk Road take down the device was intercepted while open.

It's of some frustration to me that more security devices don't have a "pull pin to destroy" function available in them for this reason if you have any type of threat model where this applies: e.g. when I thought about using a Yubikey to secure remote access, a core problem is you can't quickly wipe a Yubikey in your possession - and while they're fragile in daily use, they're also surprisingly hard to intentionally destroy quickly.
