For us who actually have customers we care about, we probably find it 
better for business to try to make sure our own customers can't announce 
prefixes they don't own, but accept basically anything from the world that 
isn't ours.

Using pure RR based filtering just isn't cost efficient today, as these 
borks (unintentional mostly) we see sometimes are few and fairly far 
between, but problems due to wrong or missing information in the RRs is 
plentyful and constant.
