Not that anyone follows the rules, but:
"Requirements for IP Version 4 Routers", Section 5.3.5, specifies:
A router [...] MUST have an option to
disable forwarding network-prefix-directed broadcasts.
That particular sentence is followed by another sentence which states
that directed-broadcast MUST default to on; obviously, the RFC
was written before the time of smurf attacks.
