Understood but it is an inexpensive first step in dealing with what can be a messy, difficult to get at repair.

You can also get PS overhaul kits, and don't forget the salvage yards.
Yeah, the big salvage yard not too far from me has gone to only metals’ recycling — no parts sales any more. :-(
But, there are a couple others in the area - it might be worth a call or drop by to see if they have any Gen 3 Outbacks in the yard.
I don’t trust myself doing a PS rebuild. An alternator, yes, but PS are really finicky, complex little buggers, and my finger dexterity just isn’t quite so good any more. :-(
That Lucas Stop Leak has a “100% Guarantee”, so, not much to lose but a bit of time & some more PS fluid. Worth a shot, though I still wonder how bad your leak was? In any event, I picked up a couple bottles this afternoon, so, I’ll see what happens.
I wonder if Lucas has the same guarantee for the engine stop leak?
It looks like the Lucas oil PS Stop Leak and the Blue Devil product require another bottle (or two?) every year or so, assuming they work on the 1st application anyway?
