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.
