I think if you leave authors alone they will be more likely to write in the first category rather than the second. After all, papers are mainly written to communicate your findings to your direct peers. So information dense isn't bad because the target audience understands.

Of course that makes it harder for people outside to penetrate but this also depends on the culture of the specific domain and there's usually people writing summaries and surveys. Great task for grad students tbh (you read a ton of papers, summarize, and by that point you should have a good understanding of what needs to be worked on in the field and not just dragged through by your advisor)
