I don't know if it is over engineered, and I can hardly argue it is when I used one microcontroller per each B7971 back in 2007 (project still available here http://groups.yahoo.com/group/smartsockets/files/ )
i think they could have done away with the main controller pic and assign it's functions to one of the tube micros and same too for the RTC, but coming from Microchip, it is designed to use as many of their products as possible I guess !
