In reply to Rodrigo Monteiro.

I would agree that customers have become accustomed to supporting redistribution of multiple routing protocols. In fact, here is a Tech Note that reviews redistributing routing protocols.
For customers that support multi-vendor networks, having the option to deploy EIGRP without having to support multiple routing protocols and redistribution points could be advantageous. By opening up EIGRP, Cisco would like to make that an option in a multi-vendor network.
