You are putting home miners versus industrial miners all over and over again, but my disapproval for Bitmain removing features from miners has nothing to do with that.
I have no idea why you are defending their decision removing features.
Obviously people want the ability back to underclock. I've been mining for nearly 6 years now. It is extremely useful in so many scenarios. It makes 0 sense and is incredibly short sighted to defend removal of the feature.
