    You are thinking of only one case. Yes, if you only mount/umount
    floppies, this makes sense. But what if you use a different access
    method, such as mtools? Each time the mtools programs are run, they
    need to re-access the same information on the disk, to examine the FAT
    tables, directories, etc. Caching this information is a big win. But
    the block device is opened/closed on every run of the program, so
    relying on the change-line to invalidate the buffers makes sense.
