This will be fixed soon – however keep in mind that server-side include_docs is no longer supported since version 3.0.0; rather any include_docs functionality is done on the client (the reason behind that the server executing the view would need to make client connections itself to get the related documents anyway).
Therefore, you are only looking at different variations of #1 (making individual requests for the documents). While this might look prettier when done on the client, it is not fundamentally different than issuing requests for the document yourself.
