Labeled Networking: Reserved vs. Implemented

I think there are fields in the IP header which are reserved for this, but very few TCP/IP stacks support any use of that field.
Implementing support for this in Linux would seem to be a simple matter of coding up the appropriate netfilter modules and adding support to iptables, the iproute2 package or other utilities to set kernel policies regarding these labels.
I'm curious what the intended application would be.
