OK. Is there any user-space library available for un-flattened tree
manipulation? I only found references to kernel unflattened tree
manipulations (drivers/of/fdt.c, include/linux/of.h) and dtc flattree.c.

Besides the indicated direction do I understand correctly that you do
not reject the series?
