Oh right, writable nested serializations, sure. I won't rehash the reasons that we don't support that in core (ill defined what behavior the user should expect) but yeah it'd still be good to have a third party package that does a decent "best effort" job of that.
My personal take on this is forget about "shitty hacks" or trying to handle this automatically, and just write the serializer create and update methods explicitly.
