What exactly is the use-case for this? Generally speaking I'm against
exposing that data structure to clients, because there will inevitably
be griping when we change it (as we most certainly will). Your
complaints boil down to "this is hard to parse from the client side",
and that already tells me you're doing something that we will refuse
to support.
