There were plenty of people saying Liquid Glass was fundamentally an utterly flawed, bad design, that even if you subjectively liked the way it looked, that its design philosophy was wrong, and led to logically consistent but unusable and ugly interfaces, all to solve a problem no one had.
I'm cautiously optimistic now that the bozo cardboard box designer dope with the ugly glasses is gone we'll see a quiet but rapid change of direction. I'll take "mea culpa". I'll take "whelp, this shit does actually just suck, here's a slider while we work on something better".
