I don't know yet if there is a point or not, I provided my view.
I think you know better than me the code in question. It might
be that I'm mistaken, and if so the good justification in the
(currently absent) cover letter may well help with that.

What do you mean? Test cases is the requirement for the new APIs
added to the lib/. It's really should be regular practice for
the code development independently on the project. If you think
frustrated by this, I can tell you that I was more than once in
the past in the same situation until I learnt it very well and
now when I submit anything to the lib I always add test cases.
