Ipv6 and the lost broadcast

Once upon a time in the ip protocol there was INADDR_BROADCAST, and all
seemed happy.

from "man ipv6":
" IPv6 supports several address types: unicast to address a single host,
  multicast  to  address a group of hosts, anycast to address the nearest
  member of a group of hosts (not implemented in Linux),
  IPv4-on-IPv6  to address a IPv4 host, and other reserved address types."

from  net/ipv6/tcp_ipv6.c +582:
...
	/*
  	 *	connect() to INADDR_ANY means loopback (BSD'ism).
  	 */
  	
  	if(ipv6_addr_any(&usin->sin6_addr))
		usin->sin6_addr.s6_addr[15] = 0x1; 
...

Why it isn't supported? Is there a particular reason to follow this
BSD'ism? 

Is it possible to achieve the same result of INADDR_BROADCAST with
multicast? The propagation has to be restricted only to the neighbour
nodes.


Best Regards
