That looks really good, great work! I added a couple of comments to make a few things a little bit clearer, but apart from that it's all good. Please merge once you've addressed the comments as you see fit :)

Suggested change

	reuseType,
	...(reuseType || { reuseType }),

We should not write this key if the reuseType is undefined

This looks potentially confusing; maybe we can still have a "reuseType" writer and simply call the "kind" writer inside? At least we would have a homogeneous logic everywhere, even if it's an unnecessary step
