Overlapping or non-overlapping VTEP pool

The question is when asking for a VTEP pool to configure ACI fabric, do you ask for non-overlapping IP pool or overlapping is OK?  I understand that the VTEP pool is only used within the fabric (for now) but with the direction of Multi-pod, multi-pod site, GOLF, the Vxlan boundary will be extended out the edge of the network thus VTEP IP will be advertised into IGP for the underlay.  That will required using a non-overlapping VTEP pool if you don't want to rebuilt your fabric.  Is this correct?
