Stock Clutch Failed at 3400 miles
The clutch pill does not make the car unfriendly to being launched. Even with the pill in there, you can side step the clutch and shock the f#ck out of the drivetrain. That pill makes the car easier to drive normally by making clutch engagement easier to modulate when shifting and taking off normally.
The Evo can launch, its just pretty well known you're going to wear clutches out when doing. Even if you have an MR, you're going to experience premature clutch wear with repeatedly launching the car.
The GSR has a two step (stationary) rev limiter from the factory, its at like 5000rpm I think.
The drivetrain can handle proper launching (proper amount of clutch slippage to avoid shocking the driveline, and avoiding wheel hop are the main concerns). In the X, you'll explode the rear diff in a higher power car, but that is solved with doing the ct9a rear diff swap.
Launching is still hard on parts, no matter what car you have. So expected repeated launch to decrease the life of certain parts. 1st gear, transmission input shaft bearings, clutch, and even the diff and tcase. But if you're doing it right, you're not going to have catastrophic failures every 3500 miles.

not even 45K, still on stock clutch
With 275 tires and tuned
I did changed though in the car the CMC and removed the clutch pill .
(the CMC is a AMS clutch kit)
And the CT9A chassis rear just as fragile as a CZ4A

I think it depends more on the course, some courses time starts when you leave the box, others start about 10-20 feet ahead of the box so you don't have to launch. And even if it's right out of the box you can assume most people won't launch so it's not going to set you back if you don't.
I went through a clutch so fast with my first wrx when I was pretty young due to launching. The tuner that put new clutch in said he had never seen one worn so much so fast. I maybe launched it 20 times. I never launch my evo because of that.

OP, 3400 miles is pretty low to burn through that clutch. Mine made it 15k with 3 seasons of autocross and mild-to-strong launches to start every run. I knew I was going to want something different anyway, so I just treated it like a wear item. As others have said, and as I look back, I don't think I would have taken that approach knowing what we know about the rear end now.
