I am SO happy they did that. Choosing 4 digits by scrolling two pairs was a nice looking stupidest idea from the beginning. The fact that you had to wait for animation to complete didn’t help. And if you didn’t wait and hit “save”, it silently used a former value. I was late at least once because of that. I also had few predefined alarms to not deal with that crap too often.
I know many ways to improve an old control, and I believe Apple has a pile of folks smarter than me who did the same, but someone stubbornly retained that and that is a win that they finally gave up.
