Cisco nexus plugin fails to create vlan on a previously used switch

When reconfiguring quantum from scratch with a cisco nexus switch that was previously used in a quantum setup, creating a VLAN might fail with:

QuantumClientException: Failed to configure Nexus:
 <config xmlns:xc="urn:ietf:params:xml:ns:netconf:base:1.0">
        <configure>
          <__XML__MODE__exec_configure>
            <vlan>
              <vlan-id-create-delete>
                <__XML__PARAM_value>582</__XML__PARAM_value>
                <__XML__MODE_vlan>
                  <name>
                    <vlan-name>q-582</vlan-name>
                  </name>
                </__XML__MODE_vlan>
              </vlan-id-create-delete>
            </vlan>
          </__XML__MODE__exec_configure>
        </configure>
      </config>
. Reason: ERROR: VLAN with the same name exists

The workaround for this is pretty easy. Just delete (even renaming seems to be enough) all the vlans that quantum is supposed to manage on the switch using the configuration console.

But couldn't the nexus plugin also simply overwrite the exisiting VLAN in case it already exists on the switch but not it the database?
