Your blog post is about yet another X Transparency, rather than about Certificate Transparency. Because CT works well people tried to apply the same approach to lots of other problems, most of them obviously dumb.

CT is a narrow solution to a narrow problem. We had that specific problem, and so this is a very good solution. You almost certainly don't have that problem, our solution can't help you, we aren't sorry about that.

Strange comment. I'm not sorry you're not sorry either.
