Will the closed chassis debugging require user authorization of some sort
and perhaps only be effective in developer mode? One of the major
concerns with the Intel SVT adapter is that it claims to work "where
USB3-hosted DCI is unavailable", including cold-boot:

There were talks about it at CCC and HITB:

Hopefully the Chromebook CCD doesn't turn into an evil-maid toolkit...
