A quick look on IRC provides this:

Granted, it's a small sample, but it proves that these [valid] addresses are
in widespread use, they do work, and there's no real reason to not use them..
Filtering on *.255 and *.0 won't catch the other broadcast/network addresses
on different subnet masks, and you wouldn't have to filter at all if the network
we properly configured =)
