Ahh.. For some reason I had convinced myself that base exfat implementations
used at least the 'keep a backup FAT' part of TexFAT, because on a terabyte
external USB drive, losing the FAT would be painful.  But if Windows 10 doesn't
do that either, then it's no great sin for Linux to not do it (and may cause
problems if Linux says "currently using FAT 2", and the disk is next used on a
Windows 10 box that only looks at FAT 1....)
