So long as we only add things, and not remove them, then any software that scans /sys/block/ shouldn't care, really.
But yes, it could go elsewhere, too. Perhaps a /sys/dev/ directory, populated with symbolic links (or hard links?) back to the /sys/block/ entries, something like this:
/sys/dev/block/8:0 -> ../../../block/sda /sys/dev/block/8:1 -> ../../../block/sda/sda1 /sys/dev/block/8:2 -> ../../../block/sda/sda2 ...
That's just a suggestion, really. And what about character devices?
Perhaps Greg will chime in.
