that's fine but who are the "informed advocates"? There is little research on this and what has been done relies on a long list of assumptions. Saying "informed advocates" feels like an "Appeal to Vague Authority" that is creating an illusion of consensus or expertise. I know Viktor Toth, one of the papers authors, and I have had conversations on this subject with him as he convinced me this is a better path than giant space born synthetic aperture optical interferometry. Yet it is cutting edge fringe and more than a century away with multiple levels of proof of concept yet to be done. Instead of promising theoretical limit, for a proper evaluation, citing lower bound expectations would be more appropriate.
