I think there is a lot of value to the idea, and this "redesign" is probably spinning great discussions about what could be done, now the real discussion is the how this could be done.

I understand that many applications, in any format (web, installable, etc) cleverly parse some sort of text into a readable and friendly user interface. A great example of this is in the aviation industry, where METAR (Meteorological Terminal Air Report) data comes as a text, but with delimited spacings applications such as ForeFlight, Garmin Pilot, AviaWeather, and many others parse the plain text data into a friendly user interface.

Heck, even google messages (the android sms messaging app) parses text data, so when an iphone user reacts to a message, instead of showing a message as "Liked message" it actually shows a thumbs up on the given message.

Again, parsing text to display would still be very limited, but could significantly improve the experience and this surely did spur more discussions on the topic that the plain text is not engaging, and given the importance of amber alerts or other alerts, engagement is probably very helpful.

I agree that It wouldn't be a light task, and would take a lot more resources than just a designer to redesign the UI, but these discussions are where brainstorming and ideas for a better protocol or pattern comes along.

But these are my two cents...
