There are some limits to what will work with draft-marques-l3vpn-end-system; I'm hoping that the authors of the VPN4DC draft will add some applicability statement language that will help to clarify what works w/an L3VPN approach in data centers and what those limits are (e.g., there are some applications and VMs for which the MAC address does matter).
Data plane learning is what networks currently do to work with existing hypervisors, and supporting it on the tenant side of the NVE helps with some incremental deployment scenarios. As has been pointed out a number of times, pure data plane learning leads to a lot of BUM traffic flooding, so a combination of data plane and control plane can work better with existing systems and improve scalability.
