OK, but please don't do what pg did a year or so ago and dismiss anyone who wrote "delve" as AI writing. I've been using "delve" in speech for 15+ years. It's just a question where and how one learns their English.
I don't buy the pro-clanker pro-em dash movement that has come out of nowhere in the past several years.
Sentences "need" very little, but without style and personality, writing becomes very boring. I suppose simplicity without any affectation works for raw communication of plain technical facts, but there's more to writing than that.
