This has always been pretty obvious to be. What has also been obvious is that writing well is a hard and rare skill which is quite distinct from other skills, skills like dancing, welding, math, physics, etc. You can be a great physicist and a great writer, or mediocre writer, or terrible writer. Some times you may have to put up with hard writing because the subject is very hard, and you're just not going to find an easier to read explanation. Just about the only subjects that can't get away with that, are frivolity and pure entertainment, they HAVE to be written well.
