This is more like an ancient and near universal practice being applied to a modern tool, rather than a totally new thing in itself.
But, for me, it does seem like we're going in a functionally poorer direction. Just a few years ago I could have a computer I could fit in my pocket. I can't buy that anymore. The fact that people are selling modifications to these devices (cross body slings, cases with those weird pop up things on the back so you can hold it one handed) to me means we've missed the mark on design. For more than a decade we had a great one handed computer that'd disappear into my pocket. No longer.
Note: the other thing I like about the SE is it was comparatively cheap. I will never get close to spending $1000 on a phone. Apple doesn’t want me anymore.
