It is unfortunately the element in the network with the shortest service 
lifecycle so the most likely to come under scrutiny for replacement. For 
ex my original core metaswitch I recently phased out survived 3 
generations of SBC's. Each generation came at not insignificant hardware 

While you say it may be a poor standard bearer it is a lever by which 
solution vendors can shoe-horn their whole NFV ecosystem into the 
carrier from the edge inward with some promise of a future-proofed 
purchase (in the form of licensing).
