Is it?
I once told a teacher I'd write ten times the number of required words as long as I could pick a subject that actually warranted it. And I followed through.
The rare times I got prompts that were actually good, I would run out of paper on which to express everything I wanted expressed. (Yes, I've done writing assignments writing by hand.)
Outside academia no-one is enforcing a word-count. Which means you can just write good prose. Using a lot of words to say very little, is not good prose.
Unless you're dealing with people that don't actually read what you write and instead just look at net weight of the word-salad you threw at them, the content of the text is what matters.
Who takes offence at only a single paragraph, if it addresses their every concern and insecurity, and they are left feeling seen as they reach the final word?
Only people who don't actually read things, or have no reading comprehension, needing the same thing said three time in different ways in one message.
