Why is @types/geojson a required dependency?

I don't think I've ever seen a type library declared as a dependency and I'm just curios as to why that is.

Yeah, I think it should be a peerDependency, does that seem right? Previously, xmldom's type signature wasn't an issue but they started shipping a type that's incompatible with the Document type you get by default with TypeScript's lib option.

Actually - @types/geojson is a peerDependency, and probably should be, though I need to confirm the particular behavior.
