Yes, many cases, because it belongs as well to firmware node.

I do not see deficiency. There is no ABI that psci must be root node, so
there is no issue to fix there.

If you want to add such ABI, I will answer: no, don't, because we do not
want paths or node names to be the ABI.

Compatible is the ABI.
