Agreed. This is a point worth emphasising: routed networking is not a panacea for everyone's networking woes. We've got a lot of NFV people and products at my employer, and while we're engaged in work to come up with L3 approaches to solve their use-cases, we'd like to draw a balance between adding complexity to the network layer to support legacy L2-based requirements and providing better native L3 solutions that NFV applications can use instead.  One of the key challenges with NFV is that it shouldn't just be a blind porting of existing codebases - you need to make sure you're producing something which takes advantage of the new environment.
