As someone who admired and aspired to Hemingway's parsimononius style of writing in my youth, nowadays I'm starting to back away from it and am growing to be more inclusive other (less concise) styles of writing.

I aspired to concision because I believed I wasn't an interesting person and didn't deserve any attention outside of the little I'm able to grab, so I kept my writing pithy in the hopes that I wouldn't have to "take up too much of anyone's time/attention".

Unfortunately, too much concision can lead to short pieces that are tiring to read -- your brain has to work harder to fill in the gaps. Sometimes "unnecessary" words are needed to help the reader feel more comfortable. Not everyone is an engineer or a technocrat. Parsimony isn't always a virtue.

There's is a place for concision, but I now believe concision is the wrong goal to aim for. Often the real goal is to create an emotional connection, and if it takes a few more words to achieve it (without belaboring the subject), so be it.

People -- often teachers -- think good writing is solely about effective communication -- to me, there has never been a wronger conclusion than this.
