I've got a question about the PaginationContainer API in Relay Modern.
When using createPaginationContainer, we're passing it a configuration object that also contains a query (as is the case in the official example).
I was wondering why we have to do that seen that there still is a QueryRenderer on the top-level that could take care of building query at the root of the hierarchy. Couldn't we just omit this second query or what's the reason that we have to include it?
I also noticed that the root query that's passed to the QueryRenderer also needs to have the first and after arguments to enable pagination. So, it seems like the QueryRenderer is still responsible to compose this query, so what's the role of the additional one that's passed to createPaginationContainer?
