Looking at this as an economic decision, were I a modern ISP, I would want

  • as few different devices as possible
  • good margins on each

and I would not care about whether the smarts were in the CPU or a controller, as my only interests would lie in solving an linear programming problem for the least cost in base cost, inventory and replacement costs.
