Currently, /proc/device-tree lays things out in a way that is
consistent w/ device tree structure.  One directory per node, one file
per property.  What you're describing would obscure this.  IMHO,
there's something to be said for having a faithful representation of
the kernel's device tree in userspace, even if some consider procfs
