It seems like you should still have an auto lock to 30 minutes? Events way less drastic than an airplane door blowing off can cause you to not be able to lock your phone, like someone just snatching it out of your hand on the subway (where in theory they could keep it awake indefinitely with a 30 minute timeout but they very probably won't)
The maximum on iOS is only 5 minutes, and I regularly leave my phone untouched for longer periods than that while cooking.
I hear your point, but everything really important on my phone is behind another wall of passwords/pin protection, and I am meticulous about backups. The physical device doesn’t matter much. I’ll put it on stolen mode remotely, force an email sign out, and just assume it’s dead because they won’t be able to turn off Find My.
I also work from home, so I’m more suited to having it in this mode of operation.
