It's a requirement per the RFC:
(from my smurf paper)
RFC 1812,
"Requirements for IP Version 4 Routers", Section 5.3.5, specifies:
---
A router MAY have an option to disable receiving network-prefix-
directed broadcasts on an interface and MUST have an option to
disable forwarding network-prefix-directed broadcasts. These options
MUST default to permit receiving and forwarding network-prefix-
directed broadcasts.
