This is a surprising threat model:

> It would be great to have the possibility to set second pin code which wipe your device without confirmations. [...] In my country (Russia, if you interested) policy try to force political activist unlock their smartphones for collect more evidence. They use tortures and threats of tortures for this. If you you can't unlock because it wiped they don't have motivation to use tortures.

My mental model of law enforcement in the US is that they don't become less inclined towards illegal violence if you anger them. If anything, I'd expect a "clear this subset of data, but go ahead and unlock the phone anyway so it looks normal" feature to be more useful.

(So I guess I think that this feature request needs more detail/discussion in order to be useful.)
