"Ignore phandle arguments in examples, when the phandle doesn't
reference a node in the example"? Although, probably can go as far as
"ignore phandle arguments in examples", since Rob's bot does
validation on examples, and should catch a mismatch where the target of
phandle exists.

I dunno if "argument" is the correct word for the RHS of the property.
