Agreed, until you have a net where 100% can understand new style
broadcasts you should leave it as the old style.

WRONG! All of the programs in the 4.3bsd distribution that broadcast
make an ioctl call to get the kernel broadcast address which is
set via /etc/ifconfig. SunOS 3.[3-4] suffers from the fact that
none of their programs that broadcast check the kernel broadcast
address and insist on using old style 4.2bsd broadcasts.
