Good ideas. For facility maintenance, as with ALL maintenance costs, they should be modable per item, so for instance armor can cost little or no maintenance, while a city might cost mainly minerals to build, but cost rads to operate.

For unit design, I'd rather the designs were given a more interesting purpose, than the design ability be removed. In SE4, at least they can be modded to have at least a little purpose to design.
