Phil,

Read RFC-985 and its recent successor. The IP address space is not flat.
There are architected IP broadcast (and other) addresses, whether bogus
or not. The intent of the martian filter is to kill "local" broadcasts
before they escape the local net. This is a pragmatic consideration
based on some years of horror living without it.
