It is intentional. As far as I can tell, this patch itself is not functional change, and is  necessary for the subsequent patch. I can add a regression test relying on the debug outputs, but I'd prefer not to, especially for what I believe is a trivial fix.

I’m not sure what is usually done in such cases, but adding a test depending on the debug outputs is better than nothing, I’m okay with that.

Anyway, I added NFCI to the title.
