On reddit I always recommend Change Map Settings and Delete Empty Chunks together, and I think there's no one using Change Map Settings who wouldn't benefit from knowing about the other mod. More lately I've started telling people about /c game.player.force.chart_all() , as this is the best way to explain why changes don't happen "immediately" because some black chunks were already generated. It helps them to be able to see.

So I ask that you mention one or both of these in the description, since people want to know them anyway.
