The funny thing is that I've been seeing this for decades. E.g.: media with a separate "subtitle (audio only)" and "subtitles (with sounds)" tracks.
Not sure why this is being presented a something new here.

They real advantage is that you don't need to create priper subtitles that are subject to different standards. So, they are cheaper.
They have different standards for stuff like how many letters to show on screen at the same time and for how long.
Pro Max buyers get "cut" too.
