If only we'd made "more than one book about worlds other than the Forgotten Realms."

Except the planes aren't universal and accessible from any setting.
What about more content for the Planes? They’re universal & can be accessed from any campaign setting, right? The DMG & PHB have only a few paragraphs on each. Separate books/modules (e.g. ToA, Avernus) for Abyss, Beastlands, Limbo, etc. could be useful to fans of any setting. Eberron has its own planar cosmology, as do the MtG settings.
And most homebrew settings I've played have their own unique cosmology too.
The planes are far from universal.

Eberron is a weird one. It's like it's own Material Plane pocket, a bubble within the D&D multiverse, but cut off from it by the Ring of Siberys.
The Magic planes are from a different multiverse entirely, accessible by denizens of the D&D multiverse, but difficult and dangerous.
