The implied context is that there is no change in runtime functionality, which
does hold true for many changes. I personally find the annotation helpful, both
for code review and when doing git archaeology. If a changelog states that the
author doesn't/didn't intend a functional change, then _any_ change in (runtime)
functionality becomes a red flag, and for me, prompts a closer look regardless of
whether or not I have other concerns with the patch/commit.
