    You can argue this about FS plugins, too. You don't need kernel support
    for cryptocompress, for example. Just have a fifo farm. Every file
    that has compression turned on is actually a named pipe, the original
    file is hidden (starts with a dot), and you have a script running to
    each fifo which runs zcat.

    The kernel support (read: interface) is just cleaner in some ways.

    In the loop mount example, it isn't universal -- the user can't CD into
    a file if they use the wrong shell, and two different shells might make
    two different mounts. How many mounts before we run out of loop devices?

    In the cryptocompress example, there's no caching or compress-on-flush
    optimization, and it isn't entirely transparent to anything. It doesn't
    look like a file, it looks like a fifo. ls will make it look yellow.
