Comment (by theMikeD):

 >I guess 'child' would take an integer and return an array with a maximum
 of one member, which would be the direct parent (since 'parent' returns
 only direct descendants ...

 You can get this already: use `get_term( $id, $tax, OBJECT )` and then
 check the `parent` parameter.

 > ... though tbh I find this naming convention to be pretty confusing).

 I do as well. IMHO `parent` is doing two different things ( returning all
 parent items, or returning children of a supplied term ) and should have
 been written as two options. I don't think repeating that decision here is
 a good idea, regardless of how my original summary is phrased and
 especially because that functionality already exists in `get_term()`.
