Ok first, et's make this clear, I am NOT proposing we switch the grid with hexes. Hexes do have their advantages, but not really what I want to plan for when designing encounters. When I say hex crawl style gaming, I mean reintroducing campaign settings that might not be incredily detailed, but have a grid or hex overlay with each hex or square maybe getting a paragraph of detail. Again, I'm not saying this should be core, I think this should be an available product in 5e for this style of gaming. See the Necromancer Games version of The Wilderlands of High Fantasy. This is arguably the best d20 setting ever released, IMHO. Each locale doesn't need 10 pages of detail, maybe just a paragraph or two of the general idea of what is there. This would be great for those of us who run sandbox style games.
