I think you've managed to hit the nail on the head.

Rather than accept the rather human nature of people writing in their own style and making mistakes, we'd prefer to filter it through a dispassionate void first.

It's rather embarrassing how quickly we're willing to toss away the human elements of writing.

Agreed. LLM writing style is disgustingly bland and "offensively inoffensive" like Corporate Memphis. Would rather have actual human style, mistakes and all.
