It's not out of fashion because of a name. It's considered dangerous because of the rate, and there is logic to that. The slow change in dogs or crops over many decades or generations is tolerable. But rapid change can kill, or at least it excites danger signals in the affected organisms (people). A car that creeps towards you slowly is fine. One that moves too fast might kill you. I think rate is the central question in this problem, but it always gets elided in discussion with the word "just," as if rate was a minor concern.
