That was meant to be a joke, albeit one with a point lurking inside it.  
The only way to truly minimize wear is not to write.

On the topic of FAT, one might imagine a vendor optimizing for the 
consumer use case.  Consumers almost always use the device as-formatted 
from the factory.  If you know that the device has a FAT filesystem with 
a known layout, you could optimize the FTL for that case.  You know that 
the FAT is a hot spot, but you know where the FAT is located, so you do 
special things to prevent wear at that virtual location.
