The other reason why I suspect it hasn't come up often is that USB sticks are so painfully slow that the file system really isn't a bottleneck.
I would expct this might be different if you were using a removable HDD (or even an SSD) with a USB 3.0 interface. In that case you really might want a bette file system than VFAT, especially if you are interchanging with another Linux system with an incompatible uid/gid namespace. That's not nearly as common a use case, though.
