The problem is that it's the first of its kind in regard to virtual
slaves/devices and many of the consumers of block device sysfs simply
weren't ready for it to appear where it did. Perhaps if it had been a
different part of sysfs hierarchy and/or linked up a different way
(virtual-slaves/?) it would have been invisible to programs that
weren't ready to consume it...
