libdevattr

I was looking at dragonfly and why they have libdevattr and we don'tI really think having udev compatible api would open the door to a lot of software, imho.I feel it wouldn't be so complicated to port dragonfly kern_udev, libprop and libdevattr from dragonfly bsd.
Am i missing a point or is this in contradiction witch any of freebsd objectives?
Let me know your thoughts...
