*EmersonF: Pure carnauba wax will not remove paint. Cleaner wax or All-in-one on the other hand, contains mild abrasives but enough only to remove minor swirl marks. This is still less aggressive than dedicated scratch/swirl removers.
I think you missed this entry from your FAQ link.
Turtle Wax > FAQs
In terms of aggressiveness, I will rank products as follows:
Heavy compound (Most aggressive)
Medium compound
Medium polish - Scratch remover, Swirl remover
Light polish - Cleaner polish, Finishing polish, Cleaner wax or All-in-one
How thick is your clear coat? How many times can you polish your car until you remove all the clear coat?
Clear coat = 50.8 microns (2 mils)
Minor swirls = 0.5-1 micron
Medium swirl = 1-2 microns
Deep scratches = 3-4 microns
Assuming you will use cleaner wax or polish every 6 months to remove minor swirls (1 micron thickness), it will take 20-25 years to completely remove all clear coat. At that time, you would need to re-paint the car.
By the way, before I had switched to Meguiar's Ultimate Wax, I personally had used Turtle Wax Carnauba Car Wax. I don't know if this is similar to Super Hard Shell version as the packaging is different.
