As discussed at:

Sphinx logger is set in a way that errors/warnings from kernel-doc are
suppressed, except when V=1.

Finding the root cause is not trivial, as we need to go into the Sphinx
overlays on the top of Python's default logger class. Instead, let's take
the trivial approach: use logger class directly. As we can later revisit
such decision, let's add a comment at the code.
