+1 Mike @FIGS articulated the stock suspension's behavior as "tip on input", which I think captures the sensation perfectly. There is just so much pitch motion before the car takes a set and digs into a turn. Doubling the front spring rate does wonders for agility on this platform. :-)
While stiffening the front may reduce rear wheel lift, it will also induce understeer which I personally wouldn't do. Sure it'll make the front end feel more responsive up to the limit of grip when it starts plowing.
The photo was taken at about 60 mph on turn in while I was still trail braking...maybe a little too much..exacerbating inner rear wheel lift. It doesn't actually lift at all in steady state cornering as I've witnessed in many other track photos.

I have not experienced the pitching sensation you describe. Maybe it's a pre '11 trait that some automotive journalists have noted. Or it's attributed to soft sidewalls and tread squirm or worn out bushings.

I'm surprised you say that as every vehicle dynamics article and YouTube video I've seen says stiffening the front relative to rear biases towards understeer and conversely stiffening the rear wrt the front biases towards oversteer. I've also experienced this myself on 3 cars I've owned. Maybe I misunderstand your point.
