What DBus API would be used to achieve this? (I can then check this
against policy)

  pinlock snap decision potentially allows malicious app to gain access

Bug description:
  Currently the pinlock dialog is implemented as snapdecision and thus
  any application that is allowed to use the notifications can
  potentially trick the user to provide his PIN code or Passcode to the
  application by invoking the pinlock dialog.

  As we want to allow applications to send normal notifications and
  snapdecisions we can't just block the whole notify service from them,
  but also we don't have any means to block just one of them.

  Thus the only solution is to remove the pinlock from snap decisions
  completely and implement a standalone dbus service for pinlock dialog
  which can be properly confined.
