Your link talks about that they're expensive to replace and shouldn't be used on track for that reason. Yep. Truth. This isn't relevant for most owners because they car never sees a track or usage that be significant enough to degrade them.
But yea if you're going to take a 200-300k car to a track, I hope you can afford 10k brake jobs. Personally I would NEVER take a 100k+ car to abuse it on the track. You can have just as much fun a 20k miata. But I'm no millionaire.

I don't think anybody "worries" about brake dust although it might kickstart their OCD tenancies. I'd love it if I never had to clean the wheels - or anything else - because no matter how well you clean it's just going to get dirty again. GT car or not.

But at what cost performance wise? I tried ceramic pads twice to reduce dust and both times I was sorry I did. Braking performance declined noticeably, particularly when cold. When dead cold they were scary bad.

As EVO magazine demonstrated with their ceramic vs iron brake test, it took over 14 crash stops from over 100mph (a completely non-real world situation) before the ceramic brakes showed any advantage and, in fact, the iron brake stopped in a shorter distance for the first few applications.

Exactly. I know that if I was ever in an emergency braking situation with cold brakes I would MUCH rather iron brakes over ceramic. Could be the difference between hitting a wall or not.

Having owned both types of brakes on Porsches, I'd choose PCCBs all day for a street car for the simple reason that, at speed, they have better feel and make it easier for me to set corner entry speeds precisely. When I drove my steel and PCCB cars back to back, the PCCBs had noticeably better feel and control at speed. That's what I loved most about them. Lack of dust was just a bonus.

I routinely towed a 7000lb trailer with the cayenne and the ceramic pads never let me down. Not all ceramics perform the same though. On my C6, Hawk ceramics were great, posi quiet were crap. The opposite on my M4 when I had it.

I'm referring to putting ceramic pads on an iron rotor car, not a car with full ceramics. Full ceramics will perform equal or better than iron and have less fade. At this level of performance, panic stops are more about tires than brakes.

I mis-understood your response...but still the independent tests show that on cold brakes, in normal city driving, in a panic stop situation, iron brakes will stop shorter on first application than ceramics brakes. That in my book makes them safer. And beside, on track, I have never been out braked by any car with PCCBs.
I think what's key is that iron brakes hold temperature longer due to more mass in rotors. Meaning PCCB cools off faster too.

I would never go back to irons unless tracking heavily. And judging from the discussions here lately, I’d guess there is a much smaller percentage of GT track rats with the 991.
