I don't believe it is "totally useless" to use separate instances for
distinct services. Configurations can get complex. Outgoing mail may
be handled differently than incoming mail. Using multiple instances can
simplify the task. While it may not *work* in this case, using multiple
instances for MX and submission services is far from *useless*.

Plenty of people would argue that Postfix experimental releases are
quite stable. In this case I would like to test and make use of postscreen.
