Yeah the general style of putting comments into questions is much better.

But that's not exactly what I meant with question-comments, I sometimes genuinely don't know why are they doing something like this, or have to ask for additional testing/evaluation/analysis/profiling results before I can decide that it's most likely not going to blow anything up. And as long as there's low probability of damage (or rather low expected value of damage) I am happy with the change :)

What really helps is a style guide. It shuts most of those pointless style nitpicks, God I hate them.
