Why don't you simply ask the one who implemented the change???

The behaviour was changed in a way that also icmp echo requests to a broadcast
address (like a ping to 192.168.1.255) are answered by the network kernal.
This is how Linux behaves and was needed for some Macintosh nfs client (and
perhaps other sw) that tries to find all systems in the local network by
sending such broadcasts.

The original network kernal simply dropped such requests...
