Sieve is all about policy.  A 5xx reject would let the sending server know the message could not be delivered due a failure. (ie: user policy rejection, without receiving MTA generating NDR backscatter).  I would rather not just accept it and the message disappear into ether without the sender receiving any notification of why.
