I think this is a valid criticism, however, if you do a search you'll see that limp mode in high heat, with track use, is not uncommon. Now, your second point as to whether the motor needs this or not is probably a "depends." I think for a street use only car it's not necessary at all. For those of us in the hotter climates of the US and who do a fair amount of track work, I think it's a reasonable addition. Previously, when I noticed my car starting to get hot I'd short shift and "go easy" for a couple of laps for it to cool down. The other issue is how long you plan to keep your vehicle. If you tend to keep your car 2-3 years, then I'd think it's not worthwhile. I keep my vehicles on average for 10 years and I think that it may help with longevity. I'm used to air-cooled track cars and when they run too hot they will loosen valve guides, pull head studs and cause other trouble. I think the S65 has shown to be pretty reliable and perhaps even bullet proof, but for me, have some additional cooling given that I'll have it for a long time is peace of mind.
