I had a brief conversation about this and the Falcon Heavy launch with my quantum professor, who is very deep into black holes. I completely understand why they're very excited about this announcement, and I am pumped as well. But they should be a bit excited for the falcon heavy launch as well, if we had a radio telescope on the far side of the moon with a decent clock the resolution on this announcement would an order of magnitude better. That kind of project will be more feasible as launches get cheaper.
edit: The radio telescope on the moon's data would be integrated into the rest of the networks, this would permit a virtual aperture diameter about ~50 times larger.
