@jakehamilton It's late here and not using the feature daily, the issues are not fresh in my mind (usually I come across a mention of an issue and am reminded). I'll check for an overview and reference there when I'm able :)
Outside of these issues I just hold a dislike for the style and flow. For me they always evoke 90s programming design patterns vs. more elegant flexibility in the default approach. But that alone is obv. not sufficient for any real opposition :)
