I had assumed an implementation that wouldn't respect this "closer to
the root" property, but that isn't the only implementation I can
imagine.

Note that you haven't really said anything at all about the relative
priority of C and D.  It could be that a "longer" tail is actually
more interesting to the client, but either way, the client has the
means of expressing an actual preference using prioritization.  In all
other cases, the server is left to guess.

Same as above.  C and D are assigned no relative weighting or
dependency, so the order in which the server allocates resources is
indeterminate.
