did adobe throw the dehaze right below the clarity
According to the April, 2018, desktop Lightroom (i.e., "Classic") release notes, "the Dehaze slider has been moved to the Basic panel, so that you can use this slider in tandem with the Clarity slider." That made sense to me, since I sometimes found I needed to adjust the Clarity setting after applying some value of Dehaze.
Both controls need to be employed judiciously, in my experience, to avoid making an image appear overcooked. I also typically find them more useful when applied locally rather than as global adjustments.
