Thomas started this discussion talking about resources, but IMHO it's 
mostly really about the scaling API. It just happens that we're 
implementing the resources first and they need to match what we 
eventually decide the API should look like.

So we're creating a new API. That doesn't happen very often. It's 
absolutely appropriate to consider whether we want two classes of 
resources in that API to have a 1:1 or 1:Many relationship, regardless 
of how many fancy transclusion things we have in the templates. For a 
start because one of the main reasons to create an API is so people can 
access it without templates.
