Sure - but from the easy of human pattern matching looking a list of hostnames in a monitoring system without needing to click to a different page I think it is worth it. If you are in the habit of moving racks, then I would agree keeping it only in an inventory system makes sense, but that also requires the asset system to be updated when a rack moves - at which point changing a hostname (which can be autogenerated by dhcp based on that system) an easy step to add.
