As a 2022 Z51 Corvette owner, I have no interest in the Z06. The flat plane crank results in inherent vibration issues that can't be good for long life and reliability. Some of these cars will be subject to great abuse on the street, others will be driven by old guys who putter around at 3 percent of the car's capability, and a few will be primarily track cars. And I agree, the oil's high zinc levels show that GM never thought these cars would get to 200,000 miles.
