Using (and providing) standard interfaces are laudible goal, however
that does not mean we can screw existing users over. Now Robin sais that
you talked to users (at least some) and this being an embedded platform
taht might be OK but generally sysfs is userspace interface and thus are
not to be changed lightly, only extended.
