Are there any parity features you are aware of that aren't receiving adequate developer/reviewer time? I'm not aware of any parity features that are in a place where throwing more engineers at them is going to speed anything up. Maybe Mark McClain (Nova parity leader) can provide some better insight here, but that is the impression I've gotten as an active Neutron contributor observing the ongoing parity work.
Given that, pointing to the Nova parity work seems a bit like a red herring. This new API is being developed orthogonally to the existing API endpoints and I don't think it was ever the expectation that Nova would switch to this during the Juno timeframe anyway. The new API will not be used during normal operation and should not impact the existing API at all.
