Which also suggests using a synthetic/sparse aperture space telescope, ie an interferometer, which could be built in exactly the same way Handmer suggests, but could actually achieve the angular resolution necessary to resolve the surface features of exoplanets.
For the record, the Twitter thread was a condensation of an article I wrote here on Substack:
