Being able to iterate rapidly might be helpful to get tech of the ground into space once we have it. But right now even Earth-bound optical interferometry is in its infancy compared to optical astronomy and radio interferometry. It is an interesting subject of research for method development, but we are far away from an instrument that is sufficiently well understood to be useful.
