There's no reason for that, and there never could have been.  127.*.*.* is
_always_ localhost.  There are many good reasons to have other names for
that host.  For instance, all of my Apache development sites get a hostname
and an ip in the 127.0.2.x range - then I can create a virtual server for
them.
