Can you expand on what isn't available? I've primarily been the one
working on different parts of splitstack, and I'm not sure what it
can't do that you need it to do :).

We might be talking about different definitions of "splitstack", as
I'm not sure what changes are required for existing services. FWIW, I
refer to what we do in CI with multinode to be splitstack in that the
nodes are already provisioned and we deploy the services on those
nodes using the same templates that we do for a "full" stack.
Those nodes could have just as easily been provisioned with our
undercloud and the services deployed using 2 separate stacks, and that
model works just as well.
