Why do you say it is broken?  What apps will it break?  Strictly
speaking I think it is fine, although not a configuration that I use.

On a laptop with a sometimes disconnected PCMCIA network card you
might find this very inconvenient.  The first configuration above will
always use the loopback address and will always be able to talk to
itself even if the network is offline since the loopback is always
available.

But this second configuration requires the network and will fail in
the case that you have taken it offline.  On laptops that is not a
desireable situation.  Even in the desktop environment there are cases
where users will take the network offline creating a similar
situation.  Applications should be able to handle either configuration
transparently.
