Goals Covered by the current proposal: Prevent any single individual from revoking our signing key. Allow a coalition of people from the Board to revoke our signing key
in case most of the people from the Board become unavailable. Allow a coalition of people, not necessarily from the Board, to
revoke our signing key in case everybody or almost everybody from
the Board becomes unavailable.
