I really don’t understand why people keep those two off. If you’re not using them they use very little battery at this point; it’s not like it was 10 years ago.

Since Apple keeps detailed usage statistics (from the people who opt in) my guess is they know how common such a behavior is and it’s obviously low enough they don’t think this change is a problem.

I agree with some of the other comments I’ve seen that this probably accomplishes what the user is trying to do (ignoring a Wi-Fi network that’s temporarily behaving poorly) and possibly protecting them (forgetting to turn it back on it running up a huge cell bill). I know I’ve heard complaints from people who accidentally did that a number of times.
