Neither this change, nor the larger set of changes I'm making in FreeBSD,
redefine the loopback network.  FreeBSD has had an IN_LOOPBACK macro for
years, with essentially the same definition as the default I provided.
The goal of my changes is to reduce the knowledge of the obsolete Class
A/B/C network structure as much as possible.  It is true that this change
makes it easier to change the system definition of the loopback network,
but I am not doing that.  It seems to me to be preferable for programs like
OpenSSH to use system definitions where possible, and not to hard-code
things like the definition of the loopback network.
