Is there anything blocking you from moving to v2?

The main problem is that v1 and v2 both have a pools resource, but v1 and v2's pool resource have different attributes.  With the way neutron wsgi works, if both v1 and v2 are enabled, it will combine both sets of attributes into the same validation schema.
