Let me clarify my statement. If you want to pass traffic on the native VLAN than you need to allow it. If the native vlan is not actually in use, IE vlan 12 is the native vlan but it is not actually being used for forwarding then you can prune it. The inter-device traffic will continue to function, such as BPDU's, CDP, PACP, LACP, etc.
