I was coming to say the same, and the descriptors being removed actually just points mote to its usefulness for writing 'in a Hemingway style'.

However, having said that I don't think the author of this article used it well, as for many reasons most any journalistic article is going to be very descriptive and use things like puns to get/maintain a reader's attention (something I personally usually hate, but not always).

I think it would be fun to create a version of this which pushes writing towards other recognizable styles like Raymond Chandler or David Foster Wallace. Maybe you pick a style from a dropdown and the analysis changes. You could possibly take it even further and automate some transformations of the input to stylize a piece of writing.

It's Hot Dog/Not Hot Dog but for creative writing.
