The handling of "ok" looks like a quirk for some broken device trees that
somehow got out of the spec. The ePAPR specification[1], chapter 2.3.4
defines a set of values for the "status" property and there is no "ok"
there.
By the way, the ePAPR specification[1] is a good thing to read on device
tree bindings, so you might want to look at it if you want to get more
information on this.

Yes, I think so.
