Ok cool. I was at first thinking the same and then thought that maybe the
'unknown' was intended to mean something like "it's definitely not in the
WC, but who knows which kind it may be in the repos".

But with that said, I agree totally.

One thing I'd like to clarify though -- this function could technically also
be used to determine the kind that may have been noted in an incomplete
node. I assume that's not worth considering for a simplicity-API.
