There are lots of completely valid IP addresses out there that end in .255. True, most of them that end in .255 ARE broadcast addresses, but if people implement this kind of filtering on a large scale, it really breaks classless IP.
Likewise, not all broadcast adresses necessarily end with .255, so filtering .255 won't help anyway in the presence of something like a /25 with a X.X.X.127 broadcast.
