Why do you find it interesting when it appears there's no real discussion between gmaxwell and the wallet's author? gmaxwell may've had some valid points, some where addressed by the author, some were opposed.
I hold gmaxwell in high regard, although in this case the feedback doesn't look very convincing. But I'm no expert on coding, which is why I'm curious to see OP's opinion on it (which I also hold in high regard).
gmaxwell's post looks more like a rant when you had a bad day and stood up with your left foot, stepping at the wrong angle and force on some leftover LEGO bricks
Lol. If the feedback turns out to be invalid, he may be willing to remove it by now.
