Review Comment:
I don't understand the rationale for using separate lists of delete files
and I think that this limits our ability to add more delete files in the future.
If we were to add a new delete file format, it would make sense to add
another list here. But clients don't know about other properties so it would
require a more invasive spec change. If instead we used an array of
`DeleteFile` that is a `oneOf` with `PositionDeleteFile` and
`EqualityDeleteFile` then clients would not be able to continue if they
encounter a different `content` type in `ContentFile`.
