Well I was hoping to "just use yaml" since yaml understands when two objects refer to the same underlying object. That means you don't have to write any logic to de-duplicate objects through relationships, etc.
Since json doesn't have the notion of referencing, that doesn't seem straightforward there. I was also hoping to "just use yaml" to avoid writing custom dumping code, since it seems in general like a useful capability. So I may yet try and find the underlying bug and fix it.
