Do you still want that even if it slows down all copy operations, and/or sometimes goes wrong due to incorrect information returned by the device/filesystem?
It's some years since I looked at this last but I have a feeling there are reasons it isn't usually done.
I think it's also something people don't run into often -- definitely not daily (or it wouldn't be a surprise after using Opus for years!) -- and will run into less and less, as we're approaching the point where FAT32's maximum volume size limit is too small for even cheap, portable USB sticks.
