I disagree. UI/UX designers often make utopic designs that would work great for the user, the engineers don't have the resources (time) or the will to execute it well and halfway through execution of the already dressed down version management pivots the team to their latest whim or fucks it up by adding a bunch of badly designed requirements meant to hack metrics. We live in a world of Frankenstein UIs and it's not the designer's fault what ends up on your screen. If you want to make a historical comparison, I'd argue that it's more likely to be in the way of working of today vs back then when UI design would get locked in much more _or_ get truly designed along the way with the product needs.
