Complexity needs to stop short of the point at which a non-negligible
fraction of intended users would struggle to deploy the system reliably
and sufficiently securely to meet their needs.  Sometimes this means
that some (deliberately left out of scope) threats remain, in order to
usably address the threats that are the primary focus of the technology.

And the system has to remain usable.  Even relatively simple systems
can be onerous to use/operate.
