I'm not suggesting documenting code in commit messages, just saying
something about the motivation/intention with the change is useful. The
message you suggest meets this criteria perfectly.

So I would say that "we forgot earlier" isn't a motivation, or
descriptive of intent (although maybe it meets the "why this is
happening" I mentioned earlier, but that was maybe poorly explained)..

Yeah, I think that's good. At least in the context I was looking at
this, trying to review the change, knowing what the intent is allows me
to check if that's been satisfied (trying to play some MIDI content with
VLC before and after).
