Usually the "reason" for things like this is that no one has written the code to do otherwise :-). PF_ROUTE is probably not a good mechanism for any bulk data transfer due to the constraints of being a datagram socket, although doing it via an interated dump rather than a simple dump operation would probably work. Sysctl is generally a better interface for monitoring for various reasona, although it also has limitations. Maintaining historic kmem support is important, since it is also the code used for interpreting core dumps, and we don't want to lose support for that.
