I see your point, it could make QoS administration easier overall for the
whole switch, or a cluster of switches. A single service policy applied to
a range of interfaces would make it easier, if that is what you mean...

What about using the same configuration for all your access ports,
independently of which vlan they belong ?
If you look at the port level, it may sound senseless, but if you look at
the switch level, it may be easier to mantain/understand.
Just a thought.
