1) Helmut should double-check, but there's no runtime dependency of any
kind (-dev package, pkg-config, linking) and the build-dep is marked as
!stage1, so should all be good on that front as far as I can tell

2) it's an end-user feature for anybody (myself being one) wanting to
use verity-protected volumes (integrity checks, possible signature
checks) on their machines
