I got a notification @ 6000 miles from the dealer informing me that my STi was due for scheduled maitenance servicing; the parking brake needed inspection/adjustment.

The parking brake isn't listed in the Service booklet provided by SOA/SOJ.

So, what gives?

We adjust it too as part of our service. Its not required and SOA doesn't require it, but it is a good thing to do as a courtesy to the customers as well as keep the E-brake lever from being a flag poll.
