A staggered tire setup makes zero sense for the stock BRZ/86, given 55F/45R weight distribution and 13 lb/hp. No good reason for wider rears.

I don't think it is *way* overestimated. Germans are using this setup for decades. It was a kind rule of thumb for rear wheel drive cars after model revisions and not necessarily only on mid- or rear- engine setups. Check here to see some results on our cars:
GR86 front 215/45R17 rear 235/45R17
GR86 best lap time
1'18"40
BRZ STI sport front and rear 215/40R18
BRZ STI sport best lap time
1'20"54
Both cars on Michelin Pilot Sport 4 tires. I believe Gazoo Racing didn't do the same on the new GR86 car mainly for cost reasons.
