Wouldn't it be better to just export the TCP metrics via it's own
file or netlink facility?

They keying of the TCP metrics is completely different from how routes
are key'd.  So I see little value in creating the illusion that these
two things live in the same keying domain.

The routing cache will be completely gone and /proc/net/rt_cache will
be an empty file.
