EVERY contact has a different custom ringtone that is no longer than 25 seconds, as well as a different custom text message tone. By this, I will know who is calling without having to take my iPhone from my pocket. I get the text messages read to me, and I will dictate a reply if not call back if it's necessary. More than that, all of the other things in iOS needing a notifier have custom ones that are louder. My ringer volume is a minimum of 90% for a reason, so that I would know these events are happening. I have operated this way since I got my XR, and for this change to happen now is extremely disappointing. This must be changed and the new tones kept for those who still wish to use them.
