This is one of the first things I always turn on with a new Mac. And I always encourage everyone on my teams to turn this on because otherwise it goes completely unnoticed until we get that huge surge of issues and product being angry because Windows users complain about it.

But I also place the blame on design teams. Most design teams I've worked with also doesn't account for this in anything they create. They usually only design for: 1: the latest macbook pro; and 2: the latest iPhone.
