But worrying about what another layer might think is a "layer violation."

Just because these are wrong doesn't make it okay for BIND to be 
wrong. ;)  (If those two jumped off a bridge, would BIND jump too?)

This is like the checknames in old BIND.  If I would have my 
druthers[1], BIND would only flag errors that are DNS (in layer) 
errors.  Any other error reporting weakens the other layers over 
time, like what we saw in sitefinder when a lot of applications had 
put a lot more semantics on a name error than they should have.
