Configurable, perhaps. But it would a mistake to make this the
default strategy.
That would make Postfix vulnerable to a trivial denial of service
attack where one bad recipient can block all mail for all other
recipients at that same site.
Imagine if I could block all mail for gmail.com in this manner.
If I understand correctly, your proposal is to treat all 4xx and
5xx delivery errors the same as a failure to connect error.
