The thing is I looked at the patch and it was far from obvious what was
going on.  Thus I put it in my queue of things to dig deeper into.  I
haven't done that digging yet.

Comments are actually important.  They often describe what the code is
supposed to do, rationale, historical context, etc.  Just because we're
changing a comment doesn't mean it's inherently trivial/obvious.

I'm generally supportive of lessening friction for developers and I
welcome proposals to do that.
