The nice thing about the holders/slave is that one can discover the topology, and potentially figure out any issues (like one path going down etc).
I also thought the sysfs hierarchy was useful, but it sounds like causes more problems than it solves. :(
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...
