I would suggest that your simplicity metric is not the right one,
simplicity is about ease of understanding and ongoing maintenace,
more than about effort to set it up. It takes more effort to build
something "simple" than to build a "mess".
Multiple instances avoid the internal complexity of a single Postfix
instance that is trying to do too much by jumping through complicated
configuration hoops.
Multiple instances also give you a more clear view of the state of
the system with clearer log entries, separate queues for filtered
and unfiltered mail, ...
Operationally a multi-instance system is easier to support. It
takes a small bit of effort to build, this is well worth it.
