At least consistent.

Like you, I can guess why they are doing this (especially given
consistency).  That doesn't make it less bad taste, more in the
spirit of the spec, or more use-friendly.  But, coming back to
your original question, I think this is permitted and questions
about "wrong" or "broken" are matters of personal opinion.
