Big assumption in my (admittedly limited) experience, plenty of SD cards seem to have different wear-leveling policies for where they think the FAT(s) will sit. I've seen card lifetimes dive by 10-100x when using ext* vs FAT (and yes I turned off all any and all metadata operations I could find :). Not a barrier if the filesystem is coming from the flash manufacturer themselves though I guess

I recall reading somewhere that some flash card manufacturers use small amounts of SLC flash for storing special information, such as FAT tables, block relocation tables and the like.
