Can you please edit this kind of thing out of your HN comments? (This is in the site guidelines: https://news.ycombinator.com/newsguidelines.html.)
It leads to a downward spiral, as one can see in the progression to https://news.ycombinator.com/item?id=42604422 and https://news.ycombinator.com/item?id=42604728. That's what we're trying to avoid here.
Your post is informative and would be just fine without the last sentence (well, plus the snarky first two words).
