I'm not an expert here either - but I do think complexity does
increase the attack service. Breaking up the control and data planes
seems like a good idea to me.

Also, devices like CPUs that run programmable logic are a target
because their logic flows can be hijacked. Hardware solutions for
simple functions like forwarding packets cannot be reprogrammed at the
data plane level, minimizing their attack service.

Moving the control plane(s) into a management domain where security
experts do their work everyday seems a must to me. Pushing this into
consumer premises and adding more and more seems like a disaster in
the making.
