[Mailmunge] Rejecting in filter_recipient vs filter_message

[list at ptld.com]

I wrote my script a few versions ago and want to make sure im following current standards.

In filter_recipient{} im using
   return Mailmunge::Response->REJECT(message => "Client blocked", code => 550, dsn => "5.7.1");

And in filter_message{} im using
   $ctx->action_bounce("Client blocked", 550, "5.7.1");
   return;

Is it still required to use the two different reject methods based on the filter_*{}, or can the same method be used in all filters? Id prefer to use the return Mailmunge::Response in all filters if possible.
