Discussed in call between Aaron and Robert: The MSFT approach to colliders by having the type be a key with separate sub-JSON would make it difficult to implement. An implementation could look for the first key, but then that would break in this case:

{
    "extensions": {}
    "box": { "size": [1, 1, 1] }
}
