Trusted port in Cat 4500-E Sup 6-E and 7-E

This is what's stated in QoS Config Guide for Cat 4500 Sup 6-E and 7-E:

" The incoming traffic is considered trusted by default. Only when the trusted boundary feature is enabled
on an interface can the port enter untrusted mode. In this mode, the switch marks the DSCP value of an
IP packet and the CoS value of the VLAN tag on the Ethernet frame as “0”. "

                

Let's say the Cat 4500 is used purely as server farm switch and the QoS policy is not to trust cos or dscp value coming from servers.

With port setting is now trusted by default, do we need to apply this command qos trust device cisco-phone (or any other equivalent command to enable trusted boundary) in all edge ports although no ip phones connected to this switch?

Thanks.
