I can't anticipate the usefulness or lack thereof of every possible
combination. Maybe we know something about the feature which indicates that
main targets can't share intermediate targets... I don't know. Anyway, I
like the arrangement because it means the implementation continues to be
simple. We can still outlaw combinations you don't like later.
