Right, I think a decent trade-off between availability and avoiding code
duplication would be to have a minimal KDS available as an option in
Keystone, with Barbican/something-else being developed in parallel as
the complex/featureful/configurable option. If Barbican/something-else
reaches feature parity, covers the "basic and simple" use case and is
integrated, we could deprecate the in-Keystone minimal-KDS option.

I know this plan looks a bit like the nova-network chronicles, but I
think the domain is more simple so feature parity is not as much of a
