Something not sparse would be nice. Also, something not focused on one smallish area of the Realms would also be nice. To date there has been no Forgotten Realms setting at all. Spelljammer is so weak that I'd need to pull out 2e to run it without having to add huge amounts to it. Dragonlance doesn't exist at all. Greyhawk doesn't exist at all. Planescape doesn't exist at all. Ravenloft, Theros, and the other new settings are like Spelljammer. You can run them, but you need to make up a whole lot to make them decent.
So far only Eberron has not been sparse.
