It sounds to me like this approach makes inappropriate
assumptions about end-users' threat models and allows
a class of malleability attacks which could range
from simple data corruption to - conceivably, under
the right circumstances - arbitrary code execution.

To me, transport _security_ does indeed require all
three of confidentiality, integrity, and
authenticity.
