We are thinking about providing extended networking configuration to
the user during environment creation through the UI, and it is
mentioned in the Networking Manager specification [1]. But we decided
to focus on improvement of use-ability and stability in Juno cycle and
many really cool features was moved to the next cycle, like manual
networking configuration of networking in the environment. We are
currently working on the roadmap for the Kilo cycle, and maybe this
feature will be available in Kilo, though no guarantee.
