 It ''can'' be helpful in some situations where a query variable is an "add
 on" — it has a default value that is otherwise assumed. "post_type" is
 probably not a great example. Ordering is, as are a number of other QVs.

 It is absolutely helpful when working with endpoints. #15178, #19243, both
 quoted above.
